Administrator-context script execution via unescaped lim parameter
Published Mar 25, 2025 · Updated Mar 25, 2025
Reflected XSS in Stylish Google Sheet Reader before 4.1 allows remote attackers to execute script in an administrator's browser. The Pages/intro.php endpoint writes the lim query parameter into the response without sanitization or output escaping. Exploitation requires a high-privilege user to open a crafted URL; the script then runs within that user's WordPress browser context.
