Unintended authenticated actions via missing CSRF protections
Published Jun 18, 2026 · Updated Jun 18, 2026
Cross-site request forgery in UBB Systems UBB.threads 7.7.5 and earlier allows attackers to make authenticated users perform unintended actions. CERT Polska reports missing CSRF protections but does not identify the affected request handlers, state-changing operations, or omitted validation. Exploitation requires an authenticated user to submit an attacker-controlled request; the specific actions and privilege-dependent impact remain undisclosed.
