What the vulnerability does
01Description
The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.33.5 via the locate_template() function. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
Explanation of Vulnerability in Simple Terms
02Summary
Page Builder by SiteOrigin versions up to 2.33.5 contain a path traversal vulnerability that allows authenticated users with low privileges to read, modify, or delete arbitrary files on the server. An attacker can bypass file access restrictions by manipulating file paths, potentially exposing sensitive configuration files, database credentials, or other protected data. Sites should update immediately to a version newer than 2.33.5.
What an attacker can do
03Attacker Capabilities
