CVE-2026-29840: n/aCVE-2026-29840

JiZhiCMS version 2.5.6 and earlier contains a stored Cross-Site Scripting (XSS) vulnerability in the release function of UserController.php. The vulnerability arises because the application attempts to sanitize input by filtering <script> tags but fails to remove dangerous event handlers such as 'onerror' in other HTML tags like <img>. An authenticated attacker can exploit this by injecting malicious scripts via the 'body' parameter in a POST request to /user/release.html. This can lead to the execution of arbitrary scripts in the context of the victim's browser, potentially compromising user data and session integrity. The CVSS score is 5.4, indicating a medium severity level.
