{"id":"GHSA-xq73-fvmr-jvmm","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.","aliases":["CVE-2026-46619"],"modified":"2026-06-26T17:56:28.218420Z","published":"2026-06-26T17:32:18Z","database_specific":{"github_reviewed_at":"2026-06-26T17:32:18Z","nvd_published_at":null,"cwe_ids":["CWE-1188","CWE-90"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-xq73-fvmr-jvmm"},{"type":"PACKAGE","url":"https://github.com/OpenIdentityPlatform/OpenAM"}],"affected":[{"package":{"name":"org.openidentityplatform.openam:openam-auth-msisdn","ecosystem":"Maven","purl":"pkg:maven/org.openidentityplatform.openam/openam-auth-msisdn"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.1.1"}]}],"versions":["14.5.2","14.5.3","14.5.4","14.6.1","14.6.2","14.6.3","14.6.4","14.6.5","14.6.6","14.7.0","14.7.1","14.7.2","14.7.3","14.7.4","14.8.1","14.8.2","14.8.3","14.8.4","15.0.0","15.0.1","15.0.2","15.0.3","15.0.4","15.1.0","15.1.1","15.1.2","15.1.3","15.1.4","15.1.5","15.1.6","15.2.0","15.2.1","15.2.2","16.0.1","16.0.2","16.0.3","16.0.4","16.0.5","16.0.6","16.1.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-xq73-fvmr-jvmm/GHSA-xq73-fvmr-jvmm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
