## What is CVE-2025-34467?

CVE-2025-34467 is a medium-severity denial of service vulnerability in fredtempez ZwiiCMS, published on 31 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

ZwiiCMS versions prior to 13.7.00 contain a denial-of-service vulnerability in multiple administrative endpoints due to improper authorization checks combined with flawed resource state management. When an authenticated low-privilege user requests an administrative page, the application returns "404 Not Found" as expected, but incorrectly acquires and associates a temporary lock on the targeted resource with the attacker session prior to authorization. This lock prevents other users, including administrators, from accessing the affected functionality until the attacker navigates away or the session is terminated.

Weakness: CWE-863 (Incorrect Authorization), CWE-667 (Improper Locking)
