CVE-2025-26903Network attack vector

Unauthorized actions via missing nonce validation

Published Apr 15, 2025 · Updated Apr 28, 2026

Cross-site request forgery in RealMag777 InPost Gallery 2.1.4.3 and earlier allows remote attackers to trigger an unauthorized action. The affected request handler does not adequately validate a WordPress nonce before accepting a forged request, but public sources do not identify the function or action. Exploitation requires a logged-in privileged user to visit a crafted page or follow a malicious link; the resulting integrity impact is limited to the victim's permissions.
