Unauthenticated stored XSS via unescaped client IP
Published Jan 24, 2022 · Updated Aug 3, 2024
Stored XSS in WP Affiliate Manager Affiliates Manager before 2.9.0 allows remote attackers to execute script via a crafted X-Forwarded-For header. The click-tracking path trusts that header as the client IP, stores it without validation or sanitization, and renders it without escaping. No authentication is required to plant the payload, but an administrator must open the click-tracking page; execution remains confined to that browser context.
