Administrator-targeted script execution via unescaped content parameter
Published May 15, 2025 · Updated May 20, 2025
Reflected XSS in sfarbota Download HTML TinyMCE Button 1.2 and earlier allows remote attackers to execute script via crafted content. The download.php endpoint inserts the POST content parameter into a script context without sanitization or output escaping. Exploitation requires an administrator or another high-privilege user to submit an attacker-controlled form, after which the script runs in that user's browser.
