CVE-2023-23801Network attack vector

Arbitrary plugin activation via missing nonce validation

Published Apr 6, 2023 · Updated Apr 28, 2026

Cross-site request forgery in HasThemes Really Simple Google Tag Manager 1.0.6 and earlier allows remote attackers to activate arbitrary plugins. The plugin_activation() function accepts a state-changing request without validating a WordPress nonce before activating the requested plugin. Exploitation requires an administrator to follow a crafted link, after which a remote attacker can activate an installed plugin but gains no reported ability to install new code.
