Technical 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.
Remediation
Check the references section for vendor advisories and patches from jizhicms. Update jizhicms to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
