CVE-2026-30964
Description
A flaw was found in web-auth/webauthn-lib. The CheckAllowedOrigins function, when configured with allowed_origins, incorrectly processes URL-like values by reducing them to their host component. This behavior ignores scheme and port differences, preventing the enforcement of precise origin policies. This could allow an attacker to bypass security restrictions, potentially leading to unauthorized information access or data manipulation.
