CVE-2025-12190Network attack vector

Bulk image optimization via missing nonce validation

Published Dec 5, 2025 · Updated Apr 8, 2026

CSRF in Image Optimizer by wps.sk 1.2.0 and earlier allows remote attackers to trigger bulk image optimization via a forged request. The imagopby_ajax_optimize_gallery() AJAX handler accepts state-changing requests without correctly validating a WordPress nonce. Exploitation requires an authenticated site administrator to act on attacker-controlled content, and the resulting action changes images in bulk.
