CVE-2026-84434
NVD: The Gravity Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.1.0.4 via the upload_file function. NVD: This is due to a mismatch between the field validation pipeline and the file persistence pipeline, where hidden file upload fields bypass extension validation and a rejected file's intact upload state is later passed to upload_file() without re-validation. NVD: This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
