Link to public exploit:

Vulnerability description

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper control of code generation in the /api/v1/validate/code endpoint when handling code submitted after obtaining a bearer token from /api/v1/auto_login. A remote attacker can obtain a superuser bearer token and submit malicious Python code to execute arbitrary code.

This affects default-configured instances where the auto-login feature is enabled and the validation endpoint is network-accessible.
