Threats affecting pkg:github/gitlawb/openclaude

A vulnerability was identified in Gitlawb openclaude up to 0.30.0. Impacted is the function waitForCallback of the file src/services/api/xaiOAuthCallback.ts of the component xAI OAuth Callback Handler. The manipulation of the argument Error leads to denial of service. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.

OpenClaude is an open-source coding-agent command line interface for cloud and local model providers. Prior to version 0.5.1, the OpenClaude MCP authentication flow starts a temporary local HTTP server to handle OAuth callbacks. To prevent CSRF attacks, the server validates a state parameter against an internally stored value. However, due to a logic flaw in the order of conditionals, an attacker can completely bypass this check and force the server to shut down — without knowing the state value at all. This issue has been patched in version 0.5.1.

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.

OpenClaude versions prior to 0.5.1 contain a path traversal vulnerability in the bashToolHasPermission() function. When the sandbox auto-allow feature is enabled without explicit deny rules, path constraints are bypassed, allowing unauthorized access to restricted directories via crafted path traversal sequences. This vulnerability is patched in version 0.5.1.
