Jizhicms
Parameter Value
CVSS 5.4 (MEDIUM)
Affected Versions before 2.5.6
Type CWE-79 (Cross-Site Scripting (XSS))
Vendor Jizhicms
Public PoC No

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.
