Name of the Vulnerable Software and Affected Versions: Firebase Admin SDK for PHP versions 3.2.0 through 3.8.0

Description: The issue is related to an Incorrect Access Control vulnerability in the src/Firebase/Auth/IdTokenVerifier.php file, which does not verify token signatures.

The attack is exploitable if the attacker knows the email address of the victim in most cases.

Recommendations: For versions 3.2.0 through 3.8.0, update to version 3.8.1 to resolve the issue.
