CVSS 3.1
8.8 highCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2024-10728
High (8.8) in wpxpo postx. EPSS 39% chance of exploitation in the next 30 days.
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.
