Name of the Vulnerable Software and Affected Versions Percona Monitoring and Management (PMM) server versions 2.x through 2.37.0

Description The issue arises from the authenticate function in auth server.go not properly formalizing and sanitizing URL paths, which fails to reject path traversal attempts. This allows an unauthenticated remote user to access protected API routes by making a crafted POST request against unauthenticated API routes, leading to escalation of privileges and information disclosure.

Recommendations For Percona Monitoring and Management (PMM) server versions 2.x through 2.37.0, update to version 2.37.1 or later to resolve the issue. As a temporary workaround, consider restricting access to unauthenticated API routes to minimize the risk of exploitation.
