CVE-2024-3962Network attack vector

Unauthenticated arbitrary file upload via missing validation

Published Apr 26, 2024 · Updated Apr 8, 2026

Unrestricted file upload in Themeisle PPOM 32.0.18 and earlier allows remote attackers to place arbitrary files on the server. The ppom_upload_file function accepts uploaded content without validating its file type before writing it to the affected site's server. Exploitation requires PPOM Pro and a WooCommerce product configured with a file-upload field to expose the required nonce; executing an uploaded server-side file grants code execution.
