Summary

agno-agi agno versions 2.7.0 to 2.7.3 and 3.0.0 to 3.0.6 are affected. The get_authentication_dependency function in auth.py fails to enforce authentication when the security_key argument is manipulated (CWE-306). A remote attacker without privileges can reach functions that should require authentication. A public exploit is available, and the project has not responded to an early issue report.
