- 9.8CriticalOct 28, 2026signalk-server Auth bypass / access controlCVE-2026-118690Signal K Server before 2.33.0 contains a missing authentication vulnerability that allows unauthenticated remote attackers to download log archives via the /skServer/ziplogs endpoint. Attackers can extract the JWT secretKey from security.json in the ZIP, forge administrator tokens, and create persistent admin accounts for full server control.
- 4.2MediumOct 23, 2026signalk-server SSRFCVE-2026-115752Signal K Server from 2.28.0-beta.2 before 2.34.0 contains a server-side request forgery vulnerability in the App Store icon fetcher that trusts absolute signalk.appIcon URLs. Attackers publishing npm packages with Signal K keywords can make servers request loopback, vessel network, or cloud metadata endpoints, storing image-typed responses served back via the admin UI.
- 5.8MediumSep 15, 2026signalk-server SSRFCVE-2026-55591Signal K Server is a server application that runs on a central hub in a boat. Prior to 2.28.0, makeRemoteRequest() in src/serverroutes.ts accepted attacker-controlled host, port, useTLS, and selfsignedcert parameters from the testSignalKConnection, requestAccess, and checkAccessRequest endpoints without validating the destination. When security was not configured, addAdminMiddleware() was a no-op in dummysecurity.ts, leaving all three endpoints accessible without authentication. The server could
- 7.5HighMay 9, 2026Signalk signal k serverCVE-2026-41893Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.25.0, the HTTP login endpoints (POST /login and POST /signalk/v1/auth/login) are protected by express-rate-limit (default: 100 attempts per 10-minute window, configurable via HTTP_RATE_LIMITS). The WebSocket login path — sending {login: {username, password}} messages over an established WebSocket connection — calls app.securityStrategy.login() directly without any rate limiting. An attacker can bypas
- 7.5HighApr 21, 2026Signalk signal k server Denial of serviceCVE-2026-39320Signal K Server is a server application that runs on a central hub in a boat. Versions prior to 2.25.0 are vulnerable to an unauthenticated Regular Expression Denial of Service (ReDoS) attack within the WebSocket subscription handling logic. By injecting unescaped regex metacharacters into the `context` parameter of a stream subscription, an attacker can force the server's Node.js event loop into a catastrophic backtracking loop when evaluating long string identifiers (like the server's self UUI
- 6.5MediumApr 2, 2026Signalk signal k serverCVE-2026-35038Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.24.0, there is an arbitrary prototype read vulnerability via `from` field bypass. This vulnerability allows a low-privileged authenticated user to bypass prototype boundary filtering to extract internal functions and properties from the global prototype object this violates data isolation and lets a user read more than they should. This issue has been patched in version 2.24.0.
- 6.1MediumApr 2, 2026Signalk signal k server Auth bypass / access controlCVE-2026-34083Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.24.0, SignalK Server contains a code-level vulnerability in its OIDC login and logout handlers where the unvalidated HTTP Host header is used to construct the OAuth2 redirect_uri. Because the redirectUri configuration is silently unset by default, an attacker can spoof the Host header to steal OAuth authorization codes and hijack user sessions in realistic deployments as The OIDC provider will then s
- 7.5HighApr 2, 2026Signalk signal k server Auth bypass / access controlCVE-2026-33951Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.24.0-beta.1, the SignalK Server exposes an unauthenticated HTTP endpoint that allows remote attackers to modify navigation data source priorities. This endpoint, accessible via PUT /signalk/v1/api/sourcePriorities, does not enforce authentication or authorization checks and directly assigns user-controlled input to the server configuration. As a result, attackers can influence which GPS, AIS, or othe
- 9.4CriticalApr 2, 2026Signalk signal k server Auth bypass / access controlCVE-2026-33950Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.24.0-beta.4, there is a privilege escalation vulnerability by Admin Role Injection via /enableSecurity. An unauthenticated attacker can gain full Administrator access to the SignalK server at any time, allowing them to modify sensitive vessel routing data, alter server configurations, and access restricted endpoints. This issue has been patched in version 2.24.0-beta.4.
- 5.0MediumFeb 2, 2026Signalk signal k server Path traversal / file handlingCVE-2026-25228Signal K Server is a server application that runs on a central hub in a boat. Prior to 2.20.3, a path traversal vulnerability in SignalK Server's applicationData API allows authenticated users on Windows systems to read, write, and list arbitrary files and directories on the filesystem. The validateAppId() function blocks forward slashes (/) but not backslashes (\), which are treated as directory separators by path.join() on Windows. This enables attackers to escape the intended applicationData
- 9.9CriticalFeb 2, 2026Signalk signal k server Code / command injectionCVE-2026-23515Signal K Server is a server application that runs on a central hub in a boat. Prior to 1.5.0, a command injection vulnerability allows authenticated users with write permissions to execute arbitrary shell commands on the Signal K server when the set-system-time plugin is enabled. Unauthenticated users can also exploit this vulnerability if security is disabled on the Signal K server. This occurs due to unsafe construction of shell commands when processing navigation.datetime values received via 4.5% likely
- 6.3MediumJan 1, 2026Signalk signal k server Auth bypass / access controlCVE-2025-69203Signal K Server is a server application that runs on a central hub in a boat. Versions prior to 2.19.0 of the access request system have two related features that when combined by themselves and with an information disclosure vulnerability enable convincing social engineering attacks against administrators. When a device creates an access request, it specifies three fields: `clientId`, `description`, and `permissions`. The SignalK admin UI displays the `description` field prominently to the admi
- 9.1CriticalJan 1, 2026Signalk signal k server Auth bypass / access controlCVE-2025-68620Signal K Server is a server application that runs on a central hub in a boat. Versions prior to 2.19.0 expose two features that can be chained together to steal JWT authentication tokens without any prior authentication. The attack combines WebSocket-based request enumeration with unauthenticated polling of access request status. The first is Unauthenticated WebSocket Request Enumeration: When a WebSocket client connects to the SignalK stream endpoint with the `serverevents=all` query parameter,
- 7.2HighJan 1, 2026Signalk signal k server Code / command injectionCVE-2025-68619Signal K Server is a server application that runs on a central hub in a boat. Versions prior to 2.19.0 of the appstore interface allow administrators to install npm packages through a REST API endpoint. While the endpoint validates that the package name exists in the npm registry as a known plugin or webapp, the version parameter accepts arbitrary npm version specifiers including URLs. npm supports installing packages from git repositories, GitHub shorthand syntax, and HTTP/HTTPS URLs pointing t
- 5.3MediumJan 1, 2026Signalk signal k server Information disclosureCVE-2025-68273Signal K Server is a server application that runs on a central hub in a boat. An unauthenticated information disclosure vulnerability in versions prior to 2.19.0 allows any user to retrieve sensitive system information, including the full SignalK data schema, connected serial devices, and installed analyzer tools. This exposure facilitates reconnaissance for further attacks. Version 2.19.0 patches the issue.NucleiDetection
- 7.5HighJan 1, 2026Signalk signal k server Denial of serviceCVE-2025-68272Signal K Server is a server application that runs on a central hub in a boat. A Denial of Service (DoS) vulnerability in versions prior to 2.19.0 allows an unauthenticated attacker to crash the SignalK Server by flooding the access request endpoint (`/signalk/v1/access/requests`). This causes a "JavaScript heap out of memory" error due to unbounded in-memory storage of request objects. Version 2.19.0 fixes the issue.
- 9.6CriticalJan 1, 2026Signalk signal k server Code / command injectionCVE-2025-66398Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.19.0, an unauthenticated attacker can pollute the internal state (`restoreFilePath`) of the server via the `/skServer/validateBackup` endpoint. This allows the attacker to hijack the administrator's "Restore" functionality to overwrite critical server configuration files (e.g., `security.json`, `package.json`), leading to account takeover and Remote Code Execution (RCE). Version 2.19.0 patches this v20% likely
