CVE-2026-92820Network attack vector

Unauthenticated file operations via unvalidated upload path

Published Oct 2, 2026 · Updated Oct 2, 2026

Arbitrary file operations in Saturday Drive Ninja Forms File Uploads 3.3.34 and earlier allow remote attackers to read, write, or delete files. The Amazon S3 upload flow stores a form-supplied path as file_path without validation, then uses it for email attachments, fetched-content writes, and scheduled deletion. Exploitation requires an External File Upload action; reading a file also requires an Email action configured to attach uploads, while writing can lead to code execution.
