SCA: security update for web-auth/webauthn-framework, web-auth/webauthn-lib (GHSA-875x-g8p7-5w27)

medium Tenable Self-Hosted Container Security Plugin ID 412500

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. The ProfileBasedRequestOptionsBuilder
 method returns allowedCredentials without any credentials if no username was found. When WebAuthn is used
 as the first or only authentication method, an attacker can enumerate usernames based on the absence of
 the `allowedCredentials` property in the assertion options response. This allows enumeration of valid or
 invalid usernames. By knowing which usernames are valid, attackers can focus their efforts on a smaller
 set of potential targets, increasing the efficiency and likelihood of successful attacks. This issue has
 been addressed in version 4.9.0 and all users are advised to upgrade. There are no known workarounds for
 this vulnerability. (CVE-2024-39912)
