Title
DeepSeek deepseek-harness Bundle Patch profile.ts loadProfile path traversal
Summary
A security flaw has been discovered in DeepSeek deepseek-harness up to 0.1.7-rc.2. The affected element is the function loadProfile of the file packages/boot/app-boot/src/profile.ts of the component Bundle Patch Handler. The manipulation of the argument dsh.bundle.patch results in path traversal. The attack may be performed from remote. The attack requires a high level of complexity. The exploitability is described as difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Title
DeepSeek Harness < 0.1.2-alpha.1 Authentication Bypass via Host Header Spoofing
Summary
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.

Title
DeepSeek deepseek-harness Bundle Patch profile.ts loadProfile path traversal
Summary
A security flaw has been discovered in DeepSeek deepseek-harness up to 0.1.7-rc.2. The affected element is the function loadProfile of the file packages/boot/app-boot/src/profile.ts of the component Bundle Patch Handler. The manipulation of the argument dsh.bundle.patch results in path traversal. The attack may be performed from remote. The attack requires a high level of complexity. The exploitability is described as difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Title
DeepSeek Harness < 0.1.2-alpha.1 Authentication Bypass via Host Header Spoofing
Summary
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.
