Description

The Post Grid Gutenberg Blocks and WordPress Blog Plugin – PostX plugin for WordPress is vulnerable to unauthorized plugin installation/activation due to a missing capability check on the 'install_required_plugin_callback' function in all versions up to, and including, 4.1.16. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate arbitrary plugins which can be leveraged to achieve remote code execution if another vulnerable plugin is installed and activated.

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.

  • wpxpo Post Grid Gutenberg Blocks for News, Magazines, Blog Websites – PostX — Up to and including 4.1.16
  • wpxpo postx_-_gutenberg_blocks_for_post_grid — Up to and including 4.1.16
