CVE-2024-37228Network attack vector

Unauthenticated file upload via missing type validation

Published Jun 24, 2024 · Updated Apr 28, 2026

Unrestricted file upload in InstaWP Connect 0.1.0.38 and earlier allows remote attackers to write arbitrary files to the WordPress server. The upload path accepts attacker-supplied files without validating their type, allowing server-executable content to reach the filesystem. No authentication or user interaction is required; public sources do not identify the responsible endpoint or function, and execution depends on server handling.
