Stored XSS via unsanitized forwarded IP address
Published Sep 25, 2023 · Updated Aug 2, 2024
Stored XSS in WPDO DoLogin Security before 3.7 allows remote attackers to inject scripts through the WordPress login form. The plugin accepts the X-Forwarded-For header as an IP address, stores it without proper sanitization, and renders it without adequate escaping. No authentication is required to submit the header, but a user must view the stored entry before the script executes in that user's browser context.
