CVE-2026-30964 Medium · 5.4 CWE-346 Mar 10, 2026
Webauthn Framework: allowed_origins collapses URL-like origins to host-only values, bypassing exact origin validation
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.
