Updated under an hour ago ()

Does this affect you?

It affects langflow-ai langflow and 1 other product. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

Langflow is a tool for building and deploying AI-powered agents and workflows. In versions prior to 1.9.0, the delete_api_key_route() endpoint accepts an api_key_id path parameter and deletes it with only a generic authentication check (get_current_active_user dependency). However, the delete_api_key() CRUD function does NOT verify that the API key belongs to the current user before deletion.
