Description

The Post Grid and Gutenberg Blocks plugin for WordPress is vulnerable to privilege escalation in all versions 2.2.87 to 2.2.90. This is due to the plugin not properly restricting what user meta values can be updated and ensuring a form is active. This makes it possible for authenticated attackers, with subscriber-level access and above, to update their user meta to become an administrator.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • pickplugins Post Grid and Gutenberg Blocks — From 2.2.87 (including) to 2.2.90 (including)
  • pickplugins post_grid — From 2.2.87 (including) to 2.2.90 (including)
