Bit Form - Information Disclosure (CVE-2024-9507)

CVE-2024-9507

The Contact Form by Bit Form: Multi Step Form, Calculation Contact Form, Payment Contact Form & Custom Contact Form builder plugin for WordPress is vulnerable to arbitrary file read in all versions up to, and including, 2.15.2 due to improper input validation within the iconUpload function. This makes it possible for authenticated attackers, with Administrator-level access and above, to leverage a PHP filter chain attack and read the contents of arbitrary files on the server, which can contain sensitive information.

Primary risk drivers: remote code execution potential

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.

What to do about this

Patch on your next cycle Worth fixing, but not ahead of other work.

Fix it

Update Bit Form to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Restrict REST API in Hack Halt Pro blocks this class of attack before WordPress processes the request.

Require authentication for REST namespaces that do not need to be public, so the API cannot be used to enumerate content and accounts.

Am I affected by this vulnerability?

You are affected if your site runs Bit Form.

How do I fix it?

Update Bit Form to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Restrict REST API in Hack Halt Pro contains this class of attack at the request layer.

What can an attacker actually do?

This is a Information Disclosure flaw. An attacker who exploits it can read data they were never meant to see, which is often the first step in a larger attack.
