CVE-2024-52377Network attack vector

Unauthenticated web-shell upload via missing type validation

Published Nov 14, 2024 · Updated Apr 28, 2026

Unrestricted file upload in BdThemes Instant Image Generator 1.5.2 and earlier allows remote attackers to place web shells on servers. An unspecified upload function accepts attacker-controlled files without validating their type before storing them in the WordPress media workflow. No authentication or user interaction is required, and executing an uploaded server-side script grants control within the web server's privileges.
