- 4.8MediumNov 3, 2026cotonti Crypto / certificateCVE-2026-121553Cotonti through 1.0.0 generates registration and email-change validation tokens with md5(microtime()), allowing attackers to bypass email-ownership verification by predicting tokens. Attackers can derive the generation time from the HTTP Date header and compute candidate tokens offline. They then submit these tokens to the users.register.php validate handler to activate accounts or confirm email addresses they do not control.
- 5.4MediumSep 28, 2026Cotonti CSRFCVE-2026-101093Cotonti through 1.0.0 contains a cross-site request forgery vulnerability in admin.users.php that allows attackers to delete user groups without token verification. Attackers can craft malicious links or pages that trick authenticated administrators into deleting custom groups and their associated permissions by riding the administrator's session.
- 5.4MediumSep 26, 2026Cotonti CSRFCVE-2026-100524Cotonti through 1.0.0 contains a cross-site request forgery vulnerability in the extensions manager that allows attackers to perform state-changing actions without anti-CSRF token validation. Attackers can craft links or embed images to force administrators to install, update, pause, or unpause extensions by tricking them into visiting a malicious page while authenticated.
- 6.1MediumSep 26, 2026CotontiCVE-2026-100523Cotonti through 1.0.0 contains an open redirect vulnerability in message.php that base64-decodes the redirect parameter without domain validation. Unauthenticated attackers can craft malicious links with encoded external URLs to redirect users to arbitrary sites via meta refresh tags for phishing attacks.
- 6.1MediumSep 26, 2026Cotonti XSSCVE-2026-100522Cotonti through 1.0.0 contains a reflected cross-site scripting vulnerability in message.php where the lng parameter is not properly escaped before output in the confirmation dialog. Unauthenticated attackers can craft malicious links with script payloads in the lng parameter to execute arbitrary JavaScript in victim browser sessions.
- 6.1MediumSep 26, 2026Cotonti XSSCVE-2026-100521Cotonti through 1.0.0 contains a reflected cross-site scripting vulnerability in the search plugin highlight parameter that performs no HTML or JavaScript escaping. Attackers can craft malicious links with injected JavaScript in the highlight parameter that executes in the browser of any visitor who opens the link, including administrators.
- 4.3MediumSep 18, 2026Cotonti CSRFCVE-2026-93873Cotonti through 1.0.0 fails to validate anti-CSRF tokens in the contact plugin submission handler, allowing attackers to forge messages. Attackers can auto-submit contact forms from attacker-controlled pages to send forged messages attributed to authenticated victims to the administrator inbox.
- 7.5HighSep 18, 2026Cotonti DeserializationCVE-2026-93872Cotonti 1.0.0 passes the base64-decoded cb parameter to unserialize() without allowed_classes restriction in the comments plugin EditAction. Registered users with comment write permissions can instantiate arbitrary PHP objects and potentially achieve file write or code execution through gadget chains.
- 5.4MediumSep 18, 2026CotontiCVE-2026-93871Cotonti through 1.0.0 fails to validate redirect destinations in page bodies prefixed with redir:, allowing authenticated users with page creation or edit permissions to store redirects to arbitrary external hosts. Attackers can craft pages on trusted domains that redirect visitors to malicious sites for phishing attacks without administrative privileges.
- 4.3MediumSep 18, 2026Cotonti CSRFCVE-2026-93870Cotonti through 1.0.0 fails to validate anti-CSRF tokens in the ratings plugin AJAX handler, allowing attackers to forge ratings on behalf of authenticated users. Attackers can craft malicious pages that auto-submit POST requests to modify stored rating data when visited by logged-in users.
- 6.1MediumSep 18, 2026CotontiCVE-2026-93869Cotonti through 1.0.0 contains an open redirect vulnerability in the cot_url_check() function that validates redirect destinations using a regular expression lacking an end-of-string anchor. Attackers can bypass the redirect guard by supplying hostnames beginning with the site domain to redirect users to attacker-controlled hosts through the ratings plugin or other redirect callers.
- 8.1HighSep 18, 2026Cotonti Crypto / certificateCVE-2026-93868Cotonti through 1.0.0 derives password recovery validation tokens from md5(microtime()) in users.passrecover.php, creating a predictable token space of approximately one million values per second. Unauthenticated attackers can read the server Date header, precompute candidate tokens within a narrow time window, and probe them against the passrecover authentication endpoint to reset any account password including administrators.
- 9.8CriticalSep 15, 2026Cotonti DeserializationCVE-2026-91939Cotonti 1.0.0 Comments plugin passes the ci GET parameter to unserialize() without allowed_classes restriction, allowing unauthenticated attackers to instantiate arbitrary PHP classes with attacker-controlled properties. Attackers can exploit PHP object injection through crafted serialized payloads to trigger gadget chains and achieve database manipulation or code execution.
- 5.4MediumJan 16, 2026cotonti siena XSSCVE-2021-47808Cotonti Siena 0.9.19 contains a stored cross-site scripting vulnerability in the admin configuration panel's site title parameter.
