Vulnerability Overview

The Ultimate Member – User Profile, User Registration, Login & Membership Plugin WordPress plugin before 2.1.20 did not properly sanitise, validate or encode the query string when generating a link to edit user's own profile, leading to an authenticated reflected Cross-Site Scripting issue. Knowledge of the targeted username is required to exploit this, and attackers would then need to make the related logged in user open a malicious link.

Technical Analysis

REMEDIATION: Update to version 2.1.20, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
