Summary

The Post Grid Gutenberg Blocks and PostX plugin for WordPress suffers from a security flaw that allows authenticated users with Subscriber-level access and above to install and activate arbitrary plugins. This vulnerability arises from a missing capability check in the 'install_required_plugin_callback' function across all versions up to 4.1.16. If another vulnerable plugin is already present, the unauthorized installation could lead to remote code execution, severely compromising the security of affected WordPress installations.

Affected Version(s)

Post Grid Gutenberg Blocks and WordPress Blog Plugin – PostX * <= 4.1.16

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
