Received Received - Intake
Local File Inclusion in SiteOrigin Page Builder Plugin Enables Code Execution

Publication date: 2026-03-03

Last updated on: 2026-03-03

Assigner: Wordfence

Description
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.

Executive Summary

The Page Builder by SiteOrigin plugin for WordPress has a Local File Inclusion vulnerability in all versions up to and including 2.33.5. This vulnerability exists in the locate_template() function.

Authenticated attackers with Contributor-level access or higher can exploit this flaw to include and execute arbitrary files on the server. This means they can run any PHP code contained in those files.

The vulnerability allows bypassing access controls and obtaining sensitive data, and it can also lead to full code execution, even when only 'safe' file types like images are uploaded and included.

Impact Analysis

This vulnerability can have severe impacts including:

  • Bypassing access controls, allowing attackers to perform actions beyond their intended permissions.
  • Execution of arbitrary PHP code on the server, which can lead to full system compromise.
  • Exposure or theft of sensitive data stored on the server.
  • Potential disruption of website functionality or service availability.
