Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 55

Description The issue is related to the implementation of the Content Security Policy (CSP) mechanism in Mozilla Firefox, specifically with the "frame-ancestors" directive. This directive's weakness can be exploited by a remote attacker to gain unauthorized access to protected information, potentially leading to a cross-origin information leak of path information.

Recommendations For versions prior to 55, update to version 55 or later to resolve the issue. As a temporary workaround, consider restricting the use of the "frame-ancestors" directive in Content Security Policy until a patch is applied.
