## Background

Proof-of-Concept script for WordPress plugin Bit File Manager version <= 6.5.7 Authenticated (Subscriber+) Limited JavaScript File Upload (CVE-2024-8743) vulnerability

## Information

Description:

The Bit File Manager – 100% Free & Open Source File Manager and Code Editor for WordPress plugin for WordPress is vulnerable to Limited JavaScript File Upload in all versions up to, and including, 6.5.7.
