User-meta deletion via missing nonce validation

Published Nov 22, 2023 · Updated Apr 8, 2026

Cross-site request forgery in Jose Lazo Delete Usermetas 1.1.2 and earlier allows remote attackers to delete arbitrary user metadata. The delumet_options_page() function processes user-meta deletion without validating a WordPress nonce on the request. Exploitation requires an administrator with an active session to act on a forged request, limiting the consequence to deletion of user metadata for arbitrary users.
