CVE-2026-42074 · OpenClaude: Sandbox Bypass via Model-Controlled `dangerouslyDisableSandbox` Input

This page contains facts from public vulnerability sources. Check the original advisory before updating.

OpenClaude is an open-source coding-agent command line interface for cloud and local model providers. Prior to version 0.5.1, the dangerouslyDisableSandbox parameter is exposed as part of the BashTool input schema, meaning the LLM (an untrusted principal per the project's own threat model) can set it to true in any tool_use response. Combined with the default allowUnsandboxedCommands: true setting, a prompt-injected model can escape the sandbox for any arbitrary command, achieving full host-level code execution. This issue has been patched in version 0.5.1.
