Reported on

Dec 31st 2021


When editing your profile, you can create social media links. However, the stored XSS vulnerability using the autofocus and onfocus attributes occurs because the double-quote is not URL-encoded in the input value of the social media link.

Proof of Concept

1. Open the and Login as to member
2. Go to "My Profile" -> "Edit Profile"
3. In the FaceBook URL field, type `asdf" autofocus onfocus="alert(document.domain)` and save.
4. Now, whenever an administrator or general user accesses my profile, XSS occurs.
