Webauthn Symfony Bundle
Monthly
The webauthn-lib PHP library before version 5.2.4 incorrectly validates origin restrictions by comparing only hostname components, allowing attackers to bypass authentication policies that rely on scheme or port differentiation. This enables an attacker to authenticate from origins that should be blocked, such as using HTTP instead of HTTPS or non-standard ports. Applications using this library with strict origin policies are affected until they upgrade to the patched version.
