CVE-2026-108789 is a medium-severity vulnerability in deepseek-ai deepseek-harness versions 0.1.1-rc.0, 0.1.1-rc.1, and 0.1.1-rc.2. It affects the agent function of the dsh-workflow-worker-thread component and allows remote enforcement of behavioral workflow manipulation. Public exploit code exists, but no known exploitation in the wild has been reported. The vendor has not responded to disclosure attempts, and no patch or remediation guidance is currently available.

CVE-2026-108788 is a medium severity vulnerability in deepseek-ai deepseek-harness versions 0.1.1-rc.0, 0.1.1-rc.1, and 0.1.1-rc.2. It involves a sandbox issue in the spawn function of the Sandbox component, triggered by manipulation of the Profile argument. The vulnerability can be exploited locally. The vendor has not responded to disclosure, and no patch is currently available. The exploit has been publicly disclosed but is not known to be used in the wild.

A path traversal vulnerability exists in DeepSeek deepseek-harness versions 0.1.7-rc.0, 0.1.7-rc.1, and 0.1.7-rc.2. The issue is in the loadProfile function of the Bundle Patch Handler component, allowing remote attackers to manipulate the dsh.bundle.patch argument to perform path traversal. Exploitation is difficult and requires a high level of complexity. The vendor has not responded to the disclosure, and no patch or fix is currently available. Public exploit code has been released, but no known active exploitation in the wild is reported. The CVSS 4.0 base score is 2.3, indicating low severity.

CVE-2026-101102 is a medium severity vulnerability in deepseek-ai deepseek-harness versions 0.1.0-rc.0 through 0.1.0-rc.7. It affects the run_code function in the Code Mode Sandbox component, resulting in a sandbox issue that can be exploited remotely. The vendor explicitly states that the sandbox is for containment only and not a security boundary. There is no vendor response or patch available at this time.

A vulnerability has been found in deepseek-ai deepseek-harness up to 0.1.7-rc.2. Affected is an unknown function of the file packages/sandbox/sandbox-local/src/profiles.ts of the component Landlock Backend. Such manipulation leads to improper isolation or compartmentalization. The attack must be carried out locally. The exploit has been disclosed to the public and may be used. It is advisable to implement a patch to correct this issue. The vendor was contacted early about this disclosure but did not respond in any way.

DeepSeek Harness versions before 0.1.2-alpha.1 contain an authentication bypass vulnerability that allows unauthenticated access to its local HTTP agent-control API by trusting a client-supplied loopback Host header instead of validating the actual TCP connection origin. This flaw enables confined processes to escape OS sandbox restrictions and escalate privileges locally. If the API port is exposed externally via tunnels or proxies, remote attackers can exploit this vulnerability to create sessions, execute arbitrary commands, and exfiltrate stored conversation transcripts without credentials.
