- Severity: CVSS 9.8 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total

- Published: 2024-04-26 · Updated: 2026-04-08

## Affected

- themeisle PPOM – Product Addons & Custom Fields for WooCommerce: through 32.0.18

## Description

The Product Addons & Fields for WooCommerce plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ppom_upload_file function in all versions up to, and including, 32.0.18. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Successful exploitation requires the PPOM Pro plugin to be installed along with a WooCommerce product that contains a file upload field to retrieve the correct nonce.
