Prior to 2.2.3, a stored cross-site scripting (XSS) vulnerability exists in the Filerise application due to improper handling of uploaded SVG files. The application accepts user-supplied SVG uploads without sanitizing or restricting embedded script content. When a malicious SVG containing inline JavaScript or event-based payloads is uploaded, it is later rendered directly in the browser whenever viewed within the application. Because SVGs are XML-based and allow scripting, they execute in the origin context of the application, enabling full stored XSS. This vulnerability is fixed in 2.2.3.","published":"2025-12-01T23:15:53.000Z","lastModified":"2026-10-18T18:10:00.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","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":["filerise/filerise"],"epss":{"score":0.00211,"percentile":0.11227,"date":"2026-10-27","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 (0.21%).
