CyberRota Analysis
AI-GeneratedDeepSeek Harness versions prior to 0.1.2-alpha.1 are vulnerable to an authentication bypass in the local HTTP control-plane API, allowing attackers to gain full control of the agent by manipulating the Host header. This critical vulnerability can lead to unauthorized execution of privileged commands, escalation of session approval policies, and access to sensitive stored data without authentication. Organizations using this software should prioritize patching to mitigate the risk of exploitation.

Original NVD Description
DeepSeek Harness before 0.1.2-alpha.1 contains an authentication bypass vulnerability that grants unauthenticated access to its local HTTP agent-control API by accepting a client-supplied loopback Host header in place of validating the actual TCP connection origin. On the default configuration, a confined tool-executed process can reach the loopback API without any port exposure and use it to escape its own OS sandbox, escalate to unconfined execution, and disable the approval prompt. When the port is externally reachable via tunnel, SSH forward, or reverse proxy, a remote attacker can exploit the same flaw to create sessions, execute arbitrary commands, and exfiltrate stored conversation transcripts without credentials.
