DeepSeek Harness Flaw Let AI Agents Disable Their Own File Sandbox Without Approval
DeepSeek Harness, an open-source tool for running artificial intelligence (AI) coding agents on developer machines, contained a flaw that allowed sandboxed agents to disable their own file sandbox protections with a single command. The vulnerability bypassed the intended security boundary that prevented agents from writing outside their designated workspace.
Why it matters: Developers using DeepSeek Harness to run AI agents on untrusted files face the risk that agents could escape sandbox restrictions and modify files outside their intended scope; review your deployment and update immediately if you use this tool.
