CVE-2026-29840 Details
Description
JiZhiCMS v2.5.6 and before contains a Stored Cross-Site Scripting (XSS) vulnerability in the release function within app/home/c/UserController.php. The application attempts to sanitize input by filtering <script> tags but fails to recursively remove dangerous event handlers in other HTML tags (such as onerror in <img> tags). This allows an authenticated remote attacker to inject arbitrary web script or HTML via the body parameter in a POST request to /user/release.html.
A stored cross-site scripting vulnerability has been identified in JiZhiCMS versions through 2.5.6. The issue resides in the release function of the UserController, where the application inadequately sanitizes input. While it filters out script tags, it fails to remove harmful event handler attributes from other HTML elements, such as the onerror attribute in image tags. This oversight enables authenticated remote attackers to inject arbitrary web scripts or HTML by exploiting the body parameter in a POST request to /user/release.html.
