{"id":"CVE-2026-123196","summary":"Authorizer before 2.4.2 Password Reset Poisoning via x-authorizer-url gRPC metadata","details":"Authorizer before 2.4.2 contains a password reset poisoning vulnerability that allows unauthenticated attackers to control emailed link hosts by supplying x-authorizer-url gRPC metadata. Attackers can send this metadata to the gRPC port or a Grpc-Metadata-X-Authorizer-Url header through the REST gateway to capture reset or magic-link tokens and take over accounts.","aliases":["GHSA-m46m-j9p5-5j99"],"modified":"2026-11-05T21:32:23.155284201Z","published":"2026-11-05T18:16:34.386Z","database_specific":{"cwe_ids":["CWE-640"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/123xxx/CVE-2026-123196.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/123xxx/CVE-2026-123196.json"},{"type":"PACKAGE","url":"https://github.com/authorizerdev/authorizer"},{"type":"ARTICLE","url":"https://github.com/authorizerdev/authorizer/blob/0bceb94f0ab726d9c396202f4d8fbedee1dc9cab/internal/gateway/mount.go#L244-L248"},{"type":"ARTICLE","url":"https://github.com/authorizerdev/authorizer/blob/0bceb94f0ab726d9c396202f4d8fbedee1dc9cab/internal/grpcsrv/transport/grpc_metadata.go#L40"},{"type":"FIX","url":"https://github.com/authorizerdev/authorizer/commit/b5012cbcdc7c32dcb4bd43179a212055e7fcb863"},{"type":"FIX","url":"https://github.com/authorizerdev/authorizer/pull/814"},{"type":"ADVISORY","url":"https://github.com/authorizerdev/authorizer/releases/tag/2.4.2"},{"type":"ADVISORY","url":"https://github.com/authorizerdev/authorizer/security/advisories/GHSA-m46m-j9p5-5j99"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-123196"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/authorizer-before-2.4.2-password-reset-poisoning-via-x-authorizer-url-grpc-metadata"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/authorizerdev/authorizer","events":[{"introduced":"c62b9acf90cb54ba62b9fb3a28fb85c823150ee8"},{"fixed":"89968b613d76f2021f4f3ef05d8a93e75f71911e"},{"fixed":"b5012cbcdc7c32dcb4bd43179a212055e7fcb863"}],"database_specific":{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"2.3.0-rc.3"},{"fixed":"2.4.2"}],"source":"AFFECTED_FIELD"},{"range":[{"fixed":"b5012cbcdc7c32dcb4bd43179a212055e7fcb863"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_TAG","original_tag":"2.4.2","range":[{"fixed":"89968b613d76f2021f4f3ef05d8a93e75f71911e"}]}]}}],"versions":["2.4.1","2.4.0","2.4.0-rc.23","2.4.0-rc.22","2.4.0-rc.21","2.4.0-rc.20","2.4.0-rc.19","2.4.0-rc.18","2.4.0-rc.17","2.4.0-rc.16","2.4.0-rc.15","2.4.0-rc.14","2.4.0-rc.13","2.4.0-rc.12","2.4.0-rc.11","2.4.0-rc.10","2.4.0-rc.9","2.4.0-rc.8","2.4.0-rc.7","2.4.0-rc.6","2.4.0-rc.5","2.4.0-rc.4","2.4.0-rc.3","2.4.0-rc.2","2.4.0-rc.1","2.4.0-rc.0","2.3.0-rc.10","2.3.0","2.3.0-rc.9","2.3.0-rc.5","2.3.0-rc.8","2.3.0-rc.7","2.3.0-rc.6","2.3.0-rc.4","2.3.0-rc.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-123196.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
