{"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":"2026-08-24T03:31:16.467866351Z","published":"2026-03-10T17:16:46.895Z","related":["CGA-226q-h7j7-3cp4"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30964.json","cna_assigner":"GitHub_M","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":"e709037fc34f4d1633233a8f0acaeebb9a0b525c"},{"fixed":"50445d659457f8350943e8f54ed1c775faac6644"},{"fixed":"535cc3c2dcbd9c3dfd5e00a254ad4a984e5e7839"},{"fixed":"b4cd9a4394c35fcac6080fd2f84f4f58a30abc01"}],"database_specific":{"extracted_events":[{"introduced":"5.2.0"},{"fixed":"5.2.4"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:spomky-labs:webauthn_framwork:*:*:*:*:*:*:*:*"}}],"versions":["5.2.3","5.2.2","5.2.0","5.2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30964.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N"}]}
