Authenticated administrative-page denial via premature resource locking
Published Dec 31, 2025 · Updated Dec 31, 2025
Denial of service in ZwiiCMS before 13.7.00 allows remote authenticated users to block administrative pages via crafted page requests. Affected endpoints acquire a temporary resource lock and bind it to the requesting session before checking whether that user is authorized. Low-privilege access is sufficient, and the lock blocks other users, including administrators, until the attacker leaves the page or the session ends.
