Description
Psono Server CE & EE versions 3.1.0 through 7.2.3 contain an authentication bypass vulnerability due to improper handling of WebAuthn challenges. An attacker with the user's password and a captured valid WebAuthn assertion can replay the assertion multiple times to bypass the WebAuthn second factor. This flaw is fixed in version 7.2.4.
