CVE-2023-44236Network attack vector

Unauthorized plugin actions via forged requests

Published Oct 9, 2023 · Updated Apr 28, 2026

CSRF in WP Captcha 2.0.0 and earlier allows remote attackers to trigger unauthorized plugin actions through a victim's authenticated browser. Patchstack has not disclosed the affected handler, request parameter, or missing request-validation operation, so the exact state change is not public. Exploitation requires victim interaction during an authenticated WordPress session, and the published CNA assessment limits reported effects to integrity and availability.
