7.2HighSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102150A function in the Kiteworks Advanced Forms component was reachable without authentication. An unauthenticated attacker could potentially use it to carry out a limited set of internal service operations on the Kiteworks platform; it did not permit access to user accounts, stored files, or form submissions.
9.4CriticalSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102149Kiteworks Email Protection Gateway did not sufficiently restrict which account a certificate could be assigned to. This could allow an attacker to associate a certificate with another user's account, affecting the confidentiality and integrity of that account's encrypted mail and, where certificate-based login is enabled, potentially permitting unauthorized access to the account.
9.3CriticalSep 30, 2026Accellion kiteworks XSSCVE-2026-102147A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an unauthenticated attacker to store crafted content that later executes arbitrary JavaScript in the authenticated session of an administrator who views the affected page. This could have permitted the attacker to gain full administrative control, including the creation of a new administrative account.
6.5MediumSep 30, 2026Accellion kiteworks Path traversal / file handlingCVE-2026-102146An authenticated Email Protection Gateway administrator holding only limited, delegated permissions could write files with attacker-controlled content to arbitrary locations accessible to the Email Protection Gateway service account. This exceeds the administrator's intended privileges and could be used to alter application files and configuration or to disrupt the availability of the service.
6.6MediumSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102145An authenticated administrator could cause the server to issue requests to, and interact with, internal network services that are not meant to be reachable through this interface. On its own this did not result in code execution.
5.3MediumSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102144A resource exhaustion vulnerability in Kiteworks Email Protection Gateway allowed an unauthenticated remote attacker to repeatedly trigger a comparatively expensive server-side operation, causing a partial denial of service.
7.5HighSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102143An unauthenticated attacker could cause a file with attacker-controlled content to be written to the appliance filesystem through an administrative upload handler that did not properly authenticate the request. This did not by itself result in code execution, which would require a separate vulnerability to place the file in an executable location.
7.2HighSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102142A system notification template on the Kiteworks appliance was rendered by a template engine that evaluated expressions contained in the stored template body. An authenticated System Administrator could potentially store a crafted template that executed operating-system commands on the appliance when the notification was next sent.
6.7MediumSep 30, 2026Accellion kiteworks Path traversal / file handlingCVE-2026-102141Two Kiteworks Core cluster-management operations did not validate file paths supplied to them, so an attacker holding root on one node of a cluster could write files as root onto another node and cause them to be executed there. Exploitation requires backend root access on a cluster node and a pending software patch present on the target node.
4.9MediumSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102140An authenticated administrator could initiate an administrative import using a file whose contents were not fully verified, because the import validated only the file's header rather than the complete file. This could allow unverified or forged content to be accepted and processed, affecting the integrity of the imported data.
6.5MediumSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102139An authorization check in the large file exchange feature of Kiteworks Email Protection Gateway did not correctly establish that the requesting user was a party to the package being requested. An authenticated user of that optional feature could read the subject, message body, and attachments of packages they neither sent nor received.
3.3LowSep 30, 2026Accellion kiteworks SSRFCVE-2026-102138An authenticated administrator on a node with an optional, separately licensed gateway role enabled could supply a connector URL that the server retrieved without sufficient validation of its scheme or destination, causing the server to issue requests to internal network services. Exploitation requires the licensed gateway role to be active.
4.1MediumSep 30, 2026Accellion kiteworks Path traversal / file handlingCVE-2026-102137An authenticated administrator could bypass the content validation applied to an administrative file upload and store a file containing dangerous content on the appliance. This did not by itself result in code execution, which would require a separate vulnerability to run the stored file.
6.3MediumSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102136In multi-node deployments, an attacker who had already obtained code execution on one appliance node could submit a value through an internal cluster interface that was written into monitoring configuration on another node without sufficient validation, potentially allowing OS commands to be executed there. Execution was limited to an unprivileged service account on that node.
6.6MediumSep 30, 2026Accellion kiteworks DeserializationCVE-2026-102135On a Kiteworks Email Protection Gateway cluster with database replication enabled, a party trusted by the cluster could submit a crafted serialized object that was deserialized without sufficient validation, potentially allowing code execution as the gateway service account. Replication is disabled by default, and exploitation requires control of a trusted cluster peer or administrative access to the appliance.
5.4MediumSep 30, 2026Accellion kiteworksCVE-2026-102134Kiteworks Core did not apply its gateway-level API security controls to every request authenticated through the platform's central authentication service. An authenticated user could reach REST API functionality over a request path on which those controls, including enforcement of signed-out and revoked sessions, were not applied.
6.6MediumSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102133An optional, separately licensed repository-connector feature in Kiteworks Core did not neutralize special characters in a user-supplied path before passing it to an external command. An authenticated system administrator could inject additional commands and write arbitrary content to files owned by the service account running the connector, enabling code execution in that account's context; exploitation additionally requires network egress from the appliance to a system under the attacker's con
7.2HighSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102132An administrative import function in Kiteworks Core did not verify that the requesting administrator was entitled to create the privileged integration credential being imported. A delegated administrator holding a single narrowly scoped administrative permission could therefore obtain full system administrator privileges, without any action by an existing system administrator.
7.2HighSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102131Kiteworks Email Protection Gateway rejected certain configuration settings, but its validation did not recognize every form in which they could be supplied. An authenticated administrator could potentially use an unrecognized form to have a file of their choosing written to the gateway and executed, resulting in code execution as the gateway service account.
7.2HighSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102130Kiteworks Email Protection Gateway did not sufficiently validate the content of an uploaded backup, and allowed an administrator to influence how the application loaded it. An authenticated administrator could potentially use this to execute arbitrary code on the gateway as the underlying service account.
7.2HighSep 30, 2026Accellion kiteworks Privilege escalationCVE-2026-102129A user-provisioning interface in Kiteworks Core did not verify that the requesting administrator was entitled to grant the role being assigned. An administrator whose delegated permissions covered role changes alone could therefore raise an account to full system-administrator privileges.
7.5HighSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102128An identity-verification weakness in Kiteworks Email Protection Gateway allowed the gateway to act on the Kiteworks platform on behalf of a user it had not authenticated, and to provision a platform account for an identity it did not already know. A remote, unauthenticated sender could potentially exploit this to obtain control of a platform account.
7.0HighSep 30, 2026Accellion kiteworksCVE-2026-102127An XML parser used by Kiteworks Email Protection Gateway did not restrict external entity references. Where an optional, non-default message-processing feature is enabled, a remote and unauthenticated sender could potentially use a crafted message to read files accessible to the gateway service account, including cryptographic key material and credentials, and have them sent to a destination they control.
8.1HighSep 30, 2026Accellion kiteworks XSSCVE-2026-102126A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an administrator holding only a single, narrowly scoped delegated permission to store crafted content that later executes arbitrary JavaScript in the authenticated session of a System Administrator who views the affected page. This could have permitted the lower-privileged administrator to escalate to full administrative control of the tenant, including the creation of a new administrative account.
8.8HighSep 30, 2026Accellion kiteworksCVE-2026-102125The sandbox that isolates document conversion on a Kiteworks appliance did not fully confine the code running inside it. Code already executing within that sandbox could potentially escape its confinement and act with the privileges of the service account that runs the application, which could allow an attacker in that position to read or modify application data and configuration, or to disrupt the service on the affected appliance.
6.5MediumSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102124A Kiteworks appliance setup interface did not enforce authentication once the appliance had completed initial configuration. An unauthenticated attacker with network access to the appliance could read and modify a limited set of setup records, including a contact name and email address captured during initial configuration.
7.4HighSep 30, 2026Accellion kiteworks Path traversal / file handlingCVE-2026-102123A Kiteworks appliance setup interface did not confine a user-supplied file path to its intended directory, which could allow an unauthenticated attacker to write a file to any location writable by the affected service account, potentially compromising the integrity of the appliance or rendering it unavailable until an operator intervenes. Exploitation requires network access to the affected interface, which is not reachable on a fully configured appliance in its default configuration; reaching i
4.3MediumSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102122Kiteworks did not correctly enforce which roles a shared folder's manager was permitted to assign. In a default configuration, an authenticated user holding the Manager role on a folder could grant the Owner role to themselves or to other members of that folder.
8.6HighSep 30, 2026Accellion kiteworks Information disclosureCVE-2026-102121A form-rendering interface in the Advanced Forms component is reachable without authentication so that published forms can be displayed to anonymous visitors, but it returned more data than the form itself required. Anyone who knew the web address of a published form could potentially retrieve the form owner's Kiteworks account profile, including personal details, along with parts of the deployment's configuration settings; no passwords, authentication tokens, or multi-factor secrets were expose
8.8HighSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102120A privilege escalation vulnerability in Kiteworks could have allowed an attacker who had already obtained code execution on one node of a clustered Kiteworks deployment to run operating system commands with elevated privileges on another node of the same cluster. Insufficient input validation in an internal cluster management function let attacker-supplied values reach a privileged execution context; exploitation requires existing access to a node in the cluster, and the affected function is not
7.2HighSep 30, 2026Accellion kiteworks Path traversal / file handlingCVE-2026-102119A path traversal weakness in an optional, non-default administrative feature allowed an authenticated administrator to move files to unintended locations outside the feature's designated directory. This could potentially be leveraged to execute arbitrary code on the underlying system.
7.8HighSep 30, 2026Accellion kiteworks Path traversal / file handlingCVE-2026-102118A local privilege escalation vulnerability in Kiteworks could have allowed an attacker with an existing shell under a low-privileged service account to escalate to root privileges on the appliance.
7.2HighSep 30, 2026Accellion kiteworksCVE-2026-102117On deployments where the remote-support capability is licensed and enabled, an authenticated System Administrator who also possessed the key protecting the submitted data could redirect the underlying system's outbound support connection to a destination of their choosing. That destination could then have operating-system commands executed on the node and receive their output, potentially resulting in remote code execution with the privileges of a local service account.
7.2HighSep 30, 2026Accellion kiteworks Path traversal / file handlingCVE-2026-102116-A weakness could have allowed an authenticated Kiteworks Email Protection Gateway administrator to write a file outside its intended location and cause the application to execute it, potentially resulting in remote code execution as the underlying service account.
9.8CriticalSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102115Kiteworks Core did not correctly validate a parameter submitted to the password reset workflow. An unauthenticated attacker who knew the email address of a user with a locally stored password could potentially reset that account's password without access to the emailed reset link and then authenticate as that user, including where the account holds administrative privileges.
7.2HighSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102114A command injection vulnerability in Kiteworks could allow a high-privileged authenticated administrator to execute arbitrary operating-system commands as root on the affected appliance node. Successful exploitation requires an administrative account with elevated privileges.
7.8HighSep 30, 2026Accellion kiteworks Path traversal / file handlingCVE-2026-102113A privilege escalation vulnerability in Kiteworks could allow an attacker who has already obtained code execution as an unprivileged backend service account on the appliance to escalate to root. A privileged routine did not safely handle a filesystem path that the lower-privileged account could influence, allowing the attacker to cause a root-owned operation to run arbitrary commands with the highest privileges. Exploitation requires existing local access to that service account.
7.8HighSep 30, 2026Accellion kiteworks Code / command injectionCVE-2026-102112A privilege escalation vulnerability in Kiteworks could allow an attacker who has already obtained code execution as an unprivileged backend service account on the appliance to escalate to root and run arbitrary commands with the highest privileges. Exploitation requires existing local access to that service account.
4.9MediumSep 30, 2026Accellion kiteworksCVE-2026-102111Kiteworks did not enforce the maximum permitted value for a configurable security-policy setting. An authenticated administrator could set this value outside its intended range so that the associated control never activated, while the control continued to appear enabled in the administrative interface and audit log, allowing it to be silently rendered ineffective.
5.9MediumSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102110An endpoint used during initial appliance setup did not require authentication and did not correctly enforce its intended state precondition, so during the initial activation window an unauthenticated network attacker could repeatedly re-trigger the privileged activation process. This could disrupt setup and leave the appliance in an incompletely configured state. The issue is only reachable while an appliance is being activated for the first time and not yet fully configured.
7.1HighSep 30, 2026Accellion kiteworks SQL injectionCVE-2026-102109A SQL injection vulnerability existed in Kiteworks Secure Data Forms, where a value derived from the authenticated user's stored account data was incorporated into a database query without proper sanitization. An authenticated user could potentially influence that value to inject SQL. Exploitation requires an authenticated session and applies only to deployments where a specific optional feature is in use.
7.2HighSep 30, 2026Accellion kiteworks DeserializationCVE-2026-102108An authenticated administrator of Kiteworks Email Protection Gateway could submit a crafted serialized object to a cluster management interface that was deserialized without sufficient validation, potentially allowing arbitrary code execution in the context of the gateway service account. Exploitation requires an administrator account holding a specific queue-management privilege.
4.6MediumSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102107Kiteworks Core contains a business logic flaw in a Kiteworks file-request feature allowed an authenticated user to send a request that appeared to originate from another user, because the server did not verify that the requester was authorized to act as the specified account. This could be used to solicit files or information from a recipient under a trusted identity; exploitation requires the feature to be enabled for the attacker's profile and the targeted recipient to act on the request.
9.1CriticalSep 30, 2026Accellion kiteworks Auth bypass / access controlCVE-2026-102106Improper authentication in a Kiteworks Email Protection Gateway administrative service. An administrative service in Kiteworks Email Protection Gateway did not consistently enforce administrator authentication, so the required password check could be bypassed. An attacker who referenced a valid administrator account could potentially create, modify, or delete internal users and managed domains and change their security-feature configuration without authenticating; deleting a managed domain also
9.1CriticalSep 30, 2026Accellion kiteworks SSRFCVE-2026-102105Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Server-Side Request Forgery (SSRF). A server-side request forgery (SSRF) weakness in Kiteworks Email Protection Gateway could allow a remote, unauthenticated attacker to induce the gateway to issue crafted requests to internal or otherwise unintended network destinations.

9.1CriticalSep 30, 2026Accellion kiteworks SSRFCVE-2026-102102Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Server-Side Request Forgery (SSRF). A server-side request forgery (SSRF) weakness in Kiteworks Email Protection Gateway could allow a remote, unauthenticated attacker to induce the gateway to issue crafted requests to internal or otherwise unintended network destinations. The requests are triggered while the gateway retrieves an issuer certificate in an inbound message. Depending on the services reachable from the gateway,
8.1HighSep 30, 2026Accellion kiteworks DeserializationCVE-2026-102101Kiteworks Core before version 9.5.0 is vulnerable to Deserialization of Untrusted Data. A deserialization weakness in Kiteworks Core could, under certain conditions, allow crafted data to be deserialized unsafely, potentially resulting in remote code execution on the appliance. Exploitation depends on an attacker first being able to influence the affected data, so this issue is not exploitable on its own.
8.7HighSep 30, 2026Accellion kiteworks XSSCVE-2026-102100Kiteworks Core before version 9.5.0 is vulnerable to Stored Cross-Site Scripting. A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an authenticated user to submit content that, when later viewed by another user, executes arbitrary JavaScript in that user's authenticated session. This could be used to perform actions on the victim's behalf and may have permitted account takeover, including of higher-privileged users. Exploitation requires the victim to view the attacker-
