A flaw was found in GitLab. This Cross-Site Scripting (XSS) vulnerability allows an unauthenticated attacker to execute arbitrary code in the context of an authenticated user's browser. This occurs when a legitimate user is convinced to visit a specially crafted webpage, potentially leading to compromised user sessions or data.
