Description

The Customizer Export/Import plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the '_import' function in all versions up to, and including, 0.9.7. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: This vulnerability is only exploitable when used in conjunction with a race condition as the uploaded file is deleted shortly after it is created.

Affected products

Customizer Export/Import: before 0.9.7.1 — fixed in 0.9.7.1

How to fix

Upgrade to a fixed version: Customizer Export/Import 0.9.7.1. Check the vendor advisory for mitigations.
