CVE-2021-36909Public exploitNetwork attack vector

Authenticated database wipe via unchecked snapshot deletion

Published Nov 18, 2021 · Updated Apr 28, 2026

Missing authorization in WP Reset PRO 5.98 and earlier allows remote authenticated users to erase a WordPress site's database. The admin_action_wpr_delete_snapshot_tables action accepts a uid query value without capability or nonce checks and uses it in a SQL LIKE pattern to select tables for deletion. Subscriber-level access is sufficient; a wildcard-like uid drops all WordPress tables, restarts installation, and enables creation of an administrator account.
