Prior to version 0.0.22, a Path Traversal vulnerability exists when using non-default configuration options `UPLOAD_DIR` and `UPLOAD_KEEP_FILENAME=True`. An attacker can write uploaded files to arbitrary locations on the filesystem by crafting a malicious filename. Users should upgrade to version 0.0.22 to receive a patch or, as a workaround, avoid using `UPLOAD_KEEP_FILENAME=True` in project configurations.","published":"2026-01-27T01:16:02.000Z","lastModified":"2026-08-07T12:17:21.000Z","status":"Modified","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-22"],"affected":["fastapiexpert/python-multipart"],"epss":{"score":0.02206,"percentile":0.82472,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2026-04-30","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":52543,"kind":"exploit","title":"Python-Multipart 0.0.22 - Path Traversal","url":"https://www.exploit-db.com/exploits/52543","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/python/webapps/52543.py","file":"exploits/python/webapps/52543.py","published":"2026-04-30","added":"2026-04-30","updated":"2026-04-30","author":"jefersoncardoso.dev","type":"webapps","platform":"python","port":null,"verified":false,"codes":["CVE-2026-24486"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"A public exploit is published in Exploit-DB and the impact is high, while EPSS rates exploitation at 2.2%.
