CVE-2022-33177Network attack vector

Unauthorized translation updates via missing URL nonces

Published Sep 6, 2022 · Updated Apr 28, 2026

Cross-site request forgery in wpdevelop Booking Calendar 9.2.1 and earlier allows remote attackers to trigger translation updates. Translation-update URLs omit nonce fields, so the server accepts a state-changing request generated through the victim's browser without verifying its origin. Exploitation requires a logged-in WordPress user with translation-update access to load an attacker-controlled request; the bounded consequence is an unauthorized translation update.
