What is CVE-2025-13761?

A vulnerability in GitLab CE/EE versions prior to 18.6.3 and 18.7.1 allowed an unauthenticated user to exploit the session of an authenticated user. By tricking the legitimate user into visiting a specially crafted webpage, it was possible for the attacker to execute arbitrary code within the context of the user's session. This presents a significant risk, potentially leading to unauthorized access and data breaches.
