{"id":"CVE-2026-30964","summary":"Webauthn Framework: allowed_origins collapses URL-like origins to host-only values, bypassing exact origin validation","details":"web-auth/webauthn-lib is an open source set of PHP libraries and a Symfony bundle to allow developers to integrate that authentication mechanism into their web applications. Prior to 5.2.4, when allowed_origins is configured, CheckAllowedOrigins reduces URL-like values to their host component and accepts on host match alone. This makes exact origin policies impossible to express: scheme and port differences are silently ignored. This vulnerability is fixed in 5.2.4.","aliases":["GHSA-f7pm-6hr8-7ggm"],"modified":"2026-04-10T05:42:42.168953Z","published":"2026-03-10T17:16:46.895Z","related":["CGA-226q-h7j7-3cp4"],"database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30964.json","cwe_ids":["CWE-346"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30964.json"},{"type":"ADVISORY","url":"https://github.com/web-auth/webauthn-framework/security/advisories/GHSA-f7pm-6hr8-7ggm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30964"},{"type":"FIX","url":"https://github.com/web-auth/webauthn-framework/commit/535cc3c2dcbd9c3dfd5e00a254ad4a984e5e7839"},{"type":"FIX","url":"https://github.com/web-auth/webauthn-framework/commit/b4cd9a4394c35fcac6080fd2f84f4f58a30abc01"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/web-auth/webauthn-framework","events":[{"introduced":"0"},{"fixed":"535cc3c2dcbd9c3dfd5e00a254ad4a984e5e7839"}]},{"type":"GIT","repo":"https://github.com/web-auth/webauthn-framework","events":[{"introduced":"0"},{"fixed":"b4cd9a4394c35fcac6080fd2f84f4f58a30abc01"}]}],"versions":["4.1.0","5.0.0","5.1.0","5.2.0","5.2.1","5.2.2","5.2.3","v1.0.0","v1.0.1","v1.1.0","v1.1.0-alpha1","v2.0.0","v2.0.0-alpha1","v2.0.1","v2.0.2","v2.0.3","v2.1.0","v2.1.1","v2.1.2","v2.1.3","v2.1.4","v2.1.5","v2.1.6","v2.1.7","v3.0.0","v3.0.1","v3.0.2","v3.2.0","v3.2.1","v3.2.2","v3.2.3","v3.2.4","v3.2.5","v3.2.6","v3.3.0","v3.3.1","v3.3.2","v3.3.3","v3.3.4","v4.0.0","v4.0.1","v4.0.2","v4.0.3","v4.0.4","v4.0.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30964.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N"}]}
