A critical vulnerability has been discovered in Rack::Static, an element of the Rack web server interface used by many Ruby applications.
The vulnerability, designated CVE-2025–27610, gives potential attackers the ability to access sensitive files via a path traversal exploit, leaving user data open to unauthenticated access.
These files can include configurations and credentials, which can be exploited by criminals for criminal activities.
