Stored XSS via unsanitized form redirect URL
Published Nov 6, 2023 · Updated Feb 26, 2025
Stored XSS in WPEverest User Registration & Membership before 3.0.4.2 allows remote authenticated users to execute script in visitors' browsers. The form settings workflow stores a javascript: URI in the Redirect URL field without sanitization, and a completed registration navigates to that value. Administrator access is required to save the payload, and a visitor must submit the affected form before script can read or alter data in that browser session.
