CVE-2026-101065: Missing authentication for critical function vulnerability
Obot is an open-source AI agent/MCP platform. In all versions up to and including commit d7e6970, the Docker quickstart command documented in the README starts the container listening on 0.0.0.0:8080 with authentication disabled by default. When authentication is disabled, every request is mapped to a synthetic "nobody" user that holds the Owner and Admin roles, so any unauthenticated party who can reach the exposed port obtains full administrative access to the Obot API and UI, including the ability to register and launch attacker-controlled MCP servers. Because the quickstart also mounts /var/run/docker.sock into the container, the MCP runtime backend reachable this way has access to the host's Docker control surface. The fix is documentation-only: the quickstart now enables authentication, and operators who followed the previous instructions should set OBOT_SERVER_ENABLE_AUTHENTICATION=true before exposing the host to any untrusted network.
