## What is CVE-2026-0722?

CVE-2026-0722 is a medium-severity SQL injection vulnerability in paultgoodchild Shield: Blocks Bots, Protects Users, and Prevents Security Breaches, published on 19 Feb 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

The Shield Security plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 21.0.8. This is due to the plugin allowing nonce verification to be bypassed via user-supplied parameter in the 'isNonceVerifyRequired' function. This makes it possible for unauthenticated attackers to execute SQL injection attacks, extracting sensitive information from the database, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
