CVE-2022-44737Network attack vector

Block-list modification via missing bulk-action nonce

Published Nov 22, 2022 · Updated Apr 28, 2026

Cross-site request forgery in TeamUpdraft AIOS 5.1.0 and earlier allows remote attackers to modify security block-list records. The process_bulk_action function accepts forged administrative requests without valid WordPress nonce verification and applies bulk changes to the plugin's block-list table. Exploitation requires an authenticated site administrator to follow a crafted link, after which records can be modified or deleted under that session.
