{"schemaVersion":3,"id":"UBUNTU-CVE-2024-49766","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Werkzeug is a Web Server Gateway Interface web application library. On Python < 3.11 on Windows, os.path.isabs() does not catch UNC paths like //server/share. Werkzeug's safe_join() relies on this check, and so can produce a path that is not safe, potentially allowing unintended access to data. Applications using Python >= 3.11, or not using Windows, are not vulnerable. Werkzeug version 3.0.6 contains a patch.","dates":{"published":"2024-10-28T00:00:00.000Z","modified":"2026-02-04T02:17:35.933Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"ubuntu","product":"python-werkzeug","name":"python-werkzeug","label":"python-werkzeug","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/python-werkzeug","purlType":"deb","versions":[{"text":"All versions","noFixRecorded":true,"fixedIn":null}],"versionsText":"All versions (No fix recorded)","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/CVE-2024-49766","label":"ubuntu.com/security/CVE-2024-49766","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2024-49766","label":"www.cve.org/CVERecord?id=CVE-2024-49766","hostname":"www.cve.org","tags":["REPORT"]},{"url":"https://github.com/pallets/werkzeug/security/advisories/GHSA-f9vj-2wh5-fj8j","label":"github.com/pallets/werkzeug/security/advisories/GHSA-f9vj-2wh5-fj8j","hostname":"github.com","tags":["REPORT"]},{"url":"https://github.com/pallets/werkzeug/commit/87cc78a25f782f8c59fbde786840a00cf0d09b3d","label":"github.com/pallets/werkzeug/commit/87cc78a25f782f8c59fbde786840a00cf0d09b3d","hostname":"github.com","tags":["REPORT"]},{"url":"https://github.com/pallets/werkzeug/commit/2767bcb10a7dd1c297d812cc5e6d11a474c1f092","label":"github.com/pallets/werkzeug/commit/2767bcb10a7dd1c297d812cc5e6d11a474c1f092","hostname":"github.com","tags":["REPORT"]},{"url":"https://github.com/pallets/werkzeug/releases/tag/3.0.6","label":"github.com/pallets/werkzeug/releases/tag/3.0.6","hostname":"github.com","tags":["REPORT"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":["CVE-2024-49766"]},"timeline":[{"kind":"published","date":"2024-10-28T00:00:00.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-02-04T02:17:35.933Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T20:06:26.260Z","stale":false,"partial":false}}
