CVE-2023-3254Network attack vector

Settings reset via missing nonce validation

Published Oct 18, 2023 · Updated Apr 8, 2026

Cross-site request forgery in Trustindex.io Widgets for Google Reviews 10.9 and earlier allows remote attackers to reset settings and remove reviews. The setup_no_reg_header.php handler accepts a state-changing request without correctly validating its WordPress nonce, so the administrator's session authorizes the reset. Exploitation requires an administrator to follow an attacker-controlled link or take an equivalent action, and the resulting integrity impact is limited to plugin settings and stored reviews.
