Name of the Vulnerable Software and Affected Versions The Grid Plus plugin for WordPress versions up to, and including, 1.3.2

Description The issue allows attackers with subscriber-level or higher access to include and execute arbitrary PHP files on the server via a shortcode attribute. This can lead to bypassing access controls, obtaining sensitive data, or achieving code execution if PHP files with arbitrary content can be uploaded and included. The issue is limited to .php files.

Recommendations For versions up to, and including, 1.3.2, update to a version higher than 1.3.2 to resolve the issue. As a temporary workaround, consider restricting access to the shortcode attribute that allows file inclusion until a patch is available.
