## What is CVE-2026-2023?

CVE-2026-2023 is a medium-severity vulnerability in brikou WP Plugin Info Card, published on 18 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 WP Plugin Info Card plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.2.0.
