CVE-2021-42364Network attack vector

Stored script injection via missing nonce validation

Published Nov 29, 2021 · Updated Feb 13, 2025

Cross-site request forgery in Stetic 1.0.6 and earlier allows remote attackers to inject stored scripts through an induced administrator request. The stats_page function in stetic.php accepts the forged request without nonce validation and stores attacker-supplied script content. Exploitation requires a logged-in administrator to submit the request, after which the script executes in site visitors' browsers.
