This repository provides an operational exploit for CVE-2025-65900, targeting Kalmia CMS v0.2.0. The exploit leverages an incorrect access control vulnerability in the /kal-api/auth/users API endpoint, allowing any authenticated user (even with read-only privileges) to retrieve all user credentials, including password hashes. The repository contains three files: a detailed README.md explaining the vulnerability and exploitation steps, the main exploit script (cve-2025-65900.py), and a requirements.txt listing dependencies (requests, colorama). The Python script automates the attack by authenticating as a low-privilege user, obtaining a JWT token from /kal-api/auth/jwt/create, and then querying /kal-api/auth/users to extract sensitive data. The hashes can be saved for offline cracking, potentially leading to full account compromise. The exploit is operational, requires valid credentials, and targets a specific version of Kalmia CMS.
