Technical details
This is a stored shortcode injection vulnerability in ProfilePress before version 4.17.1. The plugin fails to strip or sanitize shortcode syntax from the Display Name and Nickname profile fields before rendering them on public-facing pages like the member directory. An unauthenticated attacker can register an account or inject a payload during checkout, store a malicious shortcode (e.g., [profile-email], [profile-username], [profile-date-registered]) in their display name, and when other users view the member directory, the stored shortcodes execute server-side and leak sensitive data about arbitrary users. Attack vectors include registration on sites with "Anyone can register" enabled, or unauth submission via the membership checkout form with a valid plan nonce. Patches are available in version 4.17.1 and later.
