Technical details
The plugin fails to properly sanitize user input when generating wishlist pages, allowing authenticated users with contributor privilege or above to inject persistent JavaScript that executes in other users' browsers. This stored XSS requires user interaction (a privileged user must click a malicious link or visit a crafted page) but persists in the application. The vulnerability is addressed in version 4.19.0.
