Unauthorized gallery creation via cross-site request forgery

Published Feb 12, 2024 · Updated Apr 28, 2026

Cross-site request forgery in Contest Gallery 21.2.8.4 and earlier allows remote attackers to create galleries via a crafted request. Patchstack identifies gallery creation as the affected action but does not disclose the request handler or missing validation operation. Successful exploitation requires a logged-in privileged user to open or submit attacker-controlled content, causing an unwanted gallery to be added.
