CVE-2025-31921Network attack vector

Forced authenticated actions via forged cross-site requests

Published May 16, 2025 · Updated Apr 28, 2026

Cross-site request forgery in Loopus Tech WP Ultimate Tours Builder 1.055 and earlier allows remote attackers to force authenticated actions. Patchstack has not disclosed the affected endpoint or operation, and it does not identify which request-validation control fails. Exploitation requires a logged-in privileged user to visit a crafted page, click a malicious link, or submit an attacker-controlled form; the resulting action uses that user's WordPress permissions.
