Administrator-browser script execution via unescaped request parameters
Published May 15, 2023 · Updated Jan 14, 2025
Reflected XSS in Push Notifications for WordPress by PushAssist 3.0.8 and earlier allows remote attackers to run script in an administrator's browser. Multiple request parameters are returned in plugin pages without input sanitization or context-appropriate output escaping; public sources do not name the parameters or handlers. Exploitation requires a high-privilege user such as an administrator to open an attacker-crafted request, enabling script execution in that user's browser context.
