CVE-2026-14239: CWE-79 Cross-Site Scripting (XSS) in tourmaster
The tourmaster WordPress plugin before 5.4.8 does not perform a nonce check when storing a custom-filter label taken from a request parameter, and does not escape that label when echoing it on the filter admin page, allowing an unauthenticated attacker to trick a logged-in administrator into storing JavaScript that then executes in the admin area (stored Cross-Site Scripting via CSRF).
AI Analysis
Technical Summary
The tourmaster WordPress plugin versions prior to 5.4.8 contain a stored XSS vulnerability due to missing nonce verification and improper output escaping of a custom-filter label parameter. An attacker can exploit this by crafting a request that causes a logged-in administrator to store JavaScript code that executes in the admin interface, leveraging CSRF to bypass authentication requirements. This vulnerability is identified as CWE-79 (Cross-Site Scripting) and CWE-352 (Cross-Site Request Forgery). No CVSS score or official remediation level is currently provided.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary JavaScript in the context of an administrator's browser session. This can lead to administrative account compromise, unauthorized actions within the WordPress admin area, and potential site takeover or data theft. The vulnerability requires a logged-in administrator to be tricked into performing the action, leveraging CSRF to bypass authentication.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should be cautious of unsolicited requests and avoid interacting with untrusted links while logged into the WordPress admin area. Monitoring for updates from the plugin vendor is recommended.
