CVE-2026-4068Network attack vector

Arbitrary custom field deletion via missing nonce validation

Published Mar 19, 2026 · Updated Mar 19, 2026

Cross-site request forgery in Add Custom Fields to Media 2.0.3 and earlier allows remote attackers to delete custom media fields. The admin display template reads the delete GET parameter and calls update_option() without verifying a WordPress nonce. Exploitation requires a logged-in site administrator to follow a crafted link or submit a forged request, after which the targeted field configuration is removed.
