CVE, Research URL: CVE-2025-12849
Home page URL: Security reports for Photos and Files Contest Gallery – Contact Form, Upload Form, Social Share and Voting Plugin for WordPress
Application: Photos and Files Contest Gallery – Contact Form, Upload Form, Social Share and Voting Plugin for WordPress
Published on: Nov 15, 2025
Research Description: The Contest Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 28.0.2. This is due to the plugin registering the `cg_check_wp_admin_upload_v10` AJAX action for both authenticated and unauthenticated users without implementing capability checks or nonce verification. This makes it possible for unauthenticated attackers to inject arbitrary WordPress media attachments into galleries and manipulate gallery metadata via the `cg_check_wp_admin_upload_v10` action. It does not enable an attacker to move or upload files.
Affected versions: max 28.0.3.
Status: vulnerable
