CVE NOT AVAILABLE CWE-863 (opens in a new tab)How to fix?
Upgrade web-auth/webauthn-framework to version 5.3.1 or higher.
Overview
web-auth/webauthn-framework is a FIDO-U2F / FIDO2 / Webauthn Framework.
Affected versions of this package are vulnerable to Incorrect Authorization via the ClientOverridePolicy process. An attacker can bypass user verification requirements by supplying a crafted userVerification parameter in the authentication request, which overrides the server-enforced verification policy. This is only exploitable if the attacker already possesses the victim's authenticator device.
Workaround
This vulnerability can be mitigated by re-checking the isUserVerified() flag on the returned authenticator data after a successful authentication ceremony.
