This repository provides a proof-of-concept exploit for CVE-2022-25262, a vulnerability in JetBrains Hub (versions prior to 2022.1.14434) when configured as a SAML Identity Provider with the YouTrack Konnektor service enabled. The exploit consists of a Python script ('exploit.py') that runs a FastAPI web server. The server exposes an endpoint ('/get-exploit-link') which, when accessed with appropriate parameters, generates a malicious OAuth2 authorization URL targeting the victim's Hub instance. The attacker sends this link to a victim; if the victim is authenticated and completes the OAuth flow, the attacker's server receives an authorization code, which can be exchanged for a SAML response, effectively allowing SAML response takeover. The repository also includes a README.md with detailed vulnerability explanation, usage instructions, and a requirements.txt listing Python dependencies. The exploit is a working PoC and demonstrates a real attack chain, but does not include weaponized automation beyond the phishing link generation and code capture.
