{"id":"CVE-2026-113703","summary":"SuggestArr before 3.0.0 Authentication Bypass via X-Forwarded-For Spoofing","details":"SuggestArr before 3.0.0 contains an authentication bypass vulnerability in its local_bypass authentication mode where enforce_authentication() in api_service/auth/middleware.py trusts the client-controlled request.remote_addr value, which is derived from the spoofable X-Forwarded-For header due to ProxyFix(x_for=1) configuration in api_service/app.py. 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.","aliases":["GHSA-fcjm-xhw8-pmh5"],"modified":"2026-10-21T02:55:58.067674047Z","published":"2026-10-20T15:56:49.963Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/113xxx/CVE-2026-113703.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-290"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/113xxx/CVE-2026-113703.json"},{"type":"PACKAGE","url":"https://github.com/giuseppe99barchetta/SuggestArr"},{"type":"FIX","url":"https://github.com/giuseppe99barchetta/SuggestArr/releases/tag/v3.0.0"},{"type":"ADVISORY","url":"https://github.com/giuseppe99barchetta/SuggestArr/security/advisories/GHSA-fcjm-xhw8-pmh5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-113703"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/suggestarr-before-authentication-bypass-via-x-forwarded-for-spoofing"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/giuseppe99barchetta/suggestarr","events":[{"introduced":"92e0ced1a424bfc5f742b93ef46e750884e3c652"},{"fixed":"6bf5e03898cf1358af81f8aafa02691d24203b37"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"1.0.4"},{"fixed":"3.0.0"}]},{"range":[{"fixed":"6bf5e03898cf1358af81f8aafa02691d24203b37"}],"source":"REFERENCES_TAG","original_tag":"v3.0.0"}]}}],"versions":["v2.16.1","v2.16.0","v2.15.0","v2.14.1","v2.14.0","v2.13.1","v2.13.0","v2.12.0","v2.11.0","v2.10.1","v2.10.0","v2.9.1","v2.9.0","v2.8.1","v2.8.0","v2.7.3","v2.7.1","v2.7.0","v2.6.0","v2.5.0","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.2","v2.3.1","v2.3.0","v2.2.1","v2.2.0","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.1","v2.0.0","v1.0.21","v1.0.19","v1.0.18","v1.0.17","v1.0.16","v1.0.15","v1.0.14","v1.0.13","v1.0.9.1","v1.0.9","v1.0.8.3","v1.0.8.2","v1.0.8","v1.0.7","1.0.6","1.0.5","1.0.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-113703.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
