{"id":"CVE-2026-105118","summary":"OpenAM before 16.1.3 Open Redirect via Unverified id_token_hint in endSession","details":"OpenAM before 16.1.3 contains an open redirect vulnerability that allows unauthenticated attackers to redirect users by supplying an unverified id_token_hint to the /oauth2/connect/endSession endpoint. Attackers can name any realm client in a forged hint to redirect victims to any registered post-logout URI, enabling phishing that borrows the OpenAM host's trust.","aliases":["GHSA-6f8c-crwq-jqm3"],"modified":"2026-10-05T02:45:41.183235324Z","published":"2026-10-03T12:14:43.044Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105118.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-347"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105118.json"},{"type":"ADVISORY","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-6f8c-crwq-jqm3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105118"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openam-before-16.1.3-open-redirect-via-unverified-id-token-hint-in-endsession"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openidentityplatform/openam","events":[{"introduced":"0"},{"fixed":"e3cbe8470fbc44f2d9d906d0b393dc37ce6744df"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"fixed":"16.1.3"}]}}],"versions":["16.1.2","16.1.1","16.0.6","16.0.5","16.0.4","16.0.3","15.2.2","15.2.1","15.2.0","15.1.6","15.1.5","15.1.4","15.1.3","15.1.2","15.1.1","15.1.0","15.0.4","15.0.3","15.0.2","15.0.1","15.0.0","14.8.4","14.8.3","14.8.2","14.8.1","14.7.4","14.7.3","14.7.2","14.7.1","14.7.0","14.6.6","14.6.5","14.6.4","14.6.3","14.6.2","14.5.4","14.5.3","14.5.2","14.5.1","14.4.2","14.4.1","14.3.1","14.2.2","14.2.1","14.1.17","14.1.16","14.1.13","14.1.12","14.1.11","14.1.10","14.1.9","14.1.8","14.1.7","14.1.6","14.1.5","14.1.4","14.1.3","14.1.2","14.1.1","14.0.6","14.0.5","14.0.4","14.0.3","14.0.2","14.0.1","14.0.0","13.0.0","13.0.0-RC10","13.0.0-RC9","13.0.0-RC8","13.0.0-RC7","13.0.0-RC6","13.0.0-RC5","13.0.0-RC4","13.0.0-RC3","13.0.0-RC2","13.0.0-RC1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-105118.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
