About the Security Issue

The security issue addressed by this update is related to the pmpro_member shortcode. It’s a very useful and powerful shortcode to help membership site creators add personalization and build dashboard-like experiences for their members.

The pmpro_member shortcode can output any user or user meta field for the logged in user or a specific named user (by user ID).

For this reason and the potential privacy and security risks associated with displaying user info, since version 2.12.9, only administrators and users with the edit_users capability (given to people with the Administrator role) can add this shortcode to content.

Much like how WordPress core filters the script tag from content before updating the database, we also filter out this shortcode

  • If a user without the edit_users capability adds this shortcode to post content (like a page, post, or CPT), widgets, or menus, we will now remove it before saving to the database.
  • We will also remove the shortcode if it exists in post content and someone without this capability edits the post.

Upgrading to version 2.12.9 will NOT remove any existing uses of the shortcode on your site.

How to Audit Your Site For Shortcode Usage

If you are concerned with how this shortcode may have been used in your site, here’s how to audit your site:

  1. Navigate to Posts > All Posts in the WordPress admin.
  2. Search for "[pmpro_member ". Be sure to include the quotes and the space at the end.
  3. This will show you any posts that include the pmpro_member shortcode. If you weren’t using this shortcode, there may be no results.

Repeat these steps to search your Pages and any other custom post types (if applicable).
