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.","published":"2026-03-24T16:16:31.000Z","lastModified":"2026-06-17T10:29:55.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N"},"cwe":["CWE-79"],"affected":["jizhicms/jizhicms"],"epss":{"score":0.00171,"percentile":0.06457,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.17%).
