CVE-2023-29384Public exploitNetwork attack vector

Unauthenticated file upload via missing type validation

Published Dec 20, 2023 · Updated Apr 28, 2026

Unrestricted file upload in HM Plugin JobWP 2.0 and earlier allows remote attackers to place arbitrary files on the web server. The jobwp_upload_resume function accepts application attachments without validating their file type before storing them. No authentication or user interaction is required; server-side execution depends on the uploaded type being executable in the site's configuration.
