CVE-2025-4966Network attack vector

Stored cross-site scripting via missing nonce validation

Published Jun 6, 2025 · Updated Apr 8, 2026

Cross-site request forgery in WP Online Users Stats 1.0.0 and earlier allows remote attackers to inject stored scripts via forged requests. The hk_dataset_results() function processes attacker-controlled requests without validating a WordPress nonce, accepting script-bearing input that is later rendered. Exploitation requires an administrator to perform the forged action, such as following an attacker-supplied link, after which the script runs in a victim's browser.
