The endpoint derives the authorizing identity from a request-supplied value rather than the authenticated session. Only installations that configure an OAuth 1.0a site-wide consumer are affected, and exploitation requires knowledge of one of its outstanding request tokens. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which binds authorization to the logged-in session.","published":"2026-09-28T08:16:42.000Z","lastModified":"2026-09-29T16:17:12.000Z","status":"Deferred","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00421,"percentile":0.36159,"date":"2026-10-26","history":[{"date":"2026-09-28","score":0.00421,"percentile":0.3392}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.42%).
