# Bit Flows WordPress plugin: unauthenticated file inclusion runs PHP on the server

The Bit Flows WordPress plugin up to version 1.31.0 lets an unauthenticated attacker make the server include and execute a local PHP file through a webhook body field passed to an ImageHelper node. Successful exploitation can bypass access controls, expose sensitive data, or run PHP code where PHP files can be uploaded and included.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Bit Flows plugin version in the WordPress admin plugin list or with `wp plugin get bit-flows --field=version` (the plugin slug is unknown from the sources; confirm it on the install).
- Review existing Bit Flows flows for a webhook trigger that feeds a body field into an ImageHelper `imageToBase64` node.
- Confirm whether the webhook has a bearer secret or IP allowlist configured.

## Fix

- Update the Bit Flows plugin to a version later than `1.31.0`; the fixed version is unknown from the sources.
- Until patched, remove or disable flows that pipe webhook body fields into ImageHelper `imageToBase64` nodes.
- Enforce a bearer secret or IP allowlist on affected webhooks.

## From the sources

The Bit Flows: AI Agent Automation & Integrations for Forms, CRM, eCommerce, Google Sheets, and More plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.31.0 via the 'image (any body field referenced by the ImageHelper node's mix tag)' parameter parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary .php 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 .php file types can be uploaded and included. Exploitation requires that an administrator has built a webhook-triggered flow that pipes a webhook body field into an ImageHelper imageToBase64 node, and that the webhook remains in its default configuration (no bearer secret enforced, no IP allowlist set) — a legitimate and documented use case.
