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.","state":0,"publishedAt":"2026-10-20T15:56:49.963+00:00","modifiedAt":"2026-10-23T13:28:34.182+00:00","affected":[{"ecosystem":"Vendor product","name":"SuggestArr","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"giuseppe99barchetta\",\n                    \"product\": \"SuggestArr\",\n                    \"packageURL\": \"pkg:github/giuseppe99barchetta/SuggestArr\",\n                    \"repo\": \"https://github.com/giuseppe99barchetta/SuggestArr\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.0.4\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.0.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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,"severity":"CRITICAL"},{"system":"CVSS 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,"severity":"CRITICAL"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-113703","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-113703","identifiers":["CVE-2026-113703"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
