{"id":"CVE-2026-46619","aliases":["GHSA-xq73-fvmr-jvmm"],"url":"https://o3.security/vulnerability/CVE-2026-46619","summary":"OpenAM Authentication Bypass via MSISDN LDAP Injection","details":"## Summary\n\n**Description**\n\nAn LDAP Injection (CWE-90) vulnerability in the MSISDN authentication module allows an unauthenticated, remote attacker to obtain an arbitrary OpenAM session without a password in the default trusted gateway configuration. This impacts OpenAM Community Edition through version 16.0.6. This issue was patched in version 16.1.1.\n\n## Impact\nOpenAM deployments through version 16.0.6 that have MSISDN enabled are potentially affected. This enables a pre-authentication login bypass for any realm where an MSISDN module instance is enabled in an authentication chain and reachable through the trusted-gateway list, which allows all traffic by default. The request-supplied MSISDN value was concatenated directly into an LDAP search filter. The resulting OpenAM session is a normal authenticated session for the matched user.\n\n## Patch\nThis has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.","published":"2026-09-15T09:51:25.613Z","modified":"2026-10-21T10:07:27.213857698Z","cvss":null,"epss":{"score":0.00578,"percentile":0.46121,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.openidentityplatform.openam:openam-auth-msisdn","fixedVersion":"16.1.1"}],"fix":{"url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/9814d51f578341e012e4def9dc936e00dd1ce913","label":"OpenIdentityPlatform/OpenAM@9814d51"},"references":[{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46619.json"},{"type":"ADVISORY","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-xq73-fvmr-jvmm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46619"},{"type":"FIX","url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/9814d51f578341e012e4def9dc936e00dd1ce913"},{"type":"PACKAGE","url":"https://github.com/OpenIdentityPlatform/OpenAM"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T10:07:27.213857698Z"}}
