This repository provides a Python proof-of-concept exploit for CVE-2021-37580, a vulnerability in Apache ShenYu Admin (tested on version 2.4.0) that allows attackers to bypass JWT authentication. The main script, CVE-2021-37580.py, generates JWT tokens using a hardcoded secret and attempts to access the /dashboardUser endpoint to extract sensitive user data. The script supports both single-target and batch modes, using username.txt as a dictionary of usernames and url.txt for a list of target URLs. The exploit is network-based and targets HTTP(S) endpoints. The repository also includes a README with usage instructions and legal disclaimers. No weaponized or framework-based code is present; this is a standalone POC exploit.
