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.","cvss_v4":{"vector":"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","score":9.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N","score":9.3},"cwes":["CWE-290"],"references":["https://github.com/giuseppe99barchetta/SuggestArr/releases/tag/v3.0.0","https://github.com/giuseppe99barchetta/SuggestArr/security/advisories/GHSA-fcjm-xhw8-pmh5","https://www.vulncheck.com/advisories/suggestarr-before-authentication-bypass-via-x-forwarded-for-spoofing","https://github.com/giuseppe99barchetta/SuggestArr/security/advisories/GHSA-fcjm-xhw8-pmh5"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-113703","score":0.00474,"percentile":0.40705,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
