CVE-2022-2039Network attack vector

Cross-site scripting via missing nonce check

Published Jul 18, 2022 · Updated Apr 8, 2026

Cross-Site Request Forgery in LiveSupporti Free Live Chat Support 1.0.11 and earlier allows remote attackers to inject scripts via forged requests. The livesupporti_settings() function in livesupporti.php processes settings changes without verifying a WordPress nonce, allowing a cross-site request to carry attacker-controlled script content. Exploitation requires tricking a site administrator into following a link or otherwise submitting the forged request; successful exploitation can alter rendered plugin content and affect confidentiality, integrity, and availability.
