Attackers can send a request with X-Forwarded-For set to a trusted CIDR address such as 127.0.0.1 to be granted an unauthenticated admin session via _load_bypass_user_context(), gaining full administrative access to endpoints like /api/users and /api/jobs without providing any credentials.","published":"2026-10-20T16:17:13.507","modified":"2026-10-20T16:17:13.507","cvss":{"score":9.3,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/giuseppe99barchetta/SuggestArr/releases/tag/v3.0.0"},{"type":"WEB","url":"https://github.com/giuseppe99barchetta/SuggestArr/security/advisories/GHSA-fcjm-xhw8-pmh5"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/suggestarr-before-authentication-bypass-via-x-forwarded-for-spoofing"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-20T16:17:13.507"}}
