CVE-2020-37137Public exploitNetwork attack vectorHinoki check available

Administrator RCE via unsanitized panel preview

Published Feb 5, 2026 · Updated Feb 5, 2026

Eval injection in PHPFusion 9.03.50 allows remote authenticated users to execute arbitrary PHP through the panel preview function. add_panel_form() applies stripslashes() to the panel_content POST value and concatenates the result directly into an eval() expression. Access requires the administration panels endpoint, a valid aid value, and an anti-CSRF token; successful execution runs with the web application's privileges.
