Stored XSS via forged settings request
Published Aug 16, 2021 · Updated Aug 3, 2024
Stored XSS in Custom Login Redirect 1.0.0 and earlier allows remote attackers to inject script through a forged settings request. The WordPress settings handler accepts the custom_login_redirect POST value without a CSRF token, stores it without sanitization, and renders it without escaping. Exploitation requires an authenticated administrator to submit the forged request and later load the settings page, where attacker-controlled script runs in the administrator's browser context.
