CVE-2025-32579Network attack vector

Authenticated code execution via unrestricted file upload

Published Apr 11, 2025 · Updated Apr 28, 2026

Unrestricted file upload in SoftClever Limited Sync Posts 1.0 and earlier allows remote authenticated users to deploy a web shell. The plugin accepts a dangerous file type from a Subscriber-level account and stores it where the web server can execute it; public sources do not identify the handler or validation error. Subscriber access is required, and successful exploitation runs attacker-supplied server-side code with the WordPress site's web-server privileges.
