| Title | Github https://github.com/sequa-ai/sequa-mcp 0.0.1 OS Command Injection |
|---|
| Description | The Sequa MCP client has a flawed implementation where it fails to sanitize metadata during OAuth server discovery. Specifically, the authorization_endpoint URL provided by the server is passed directly to an insecure open function. An attacker can exploit this by embedding a payload in the URL's authentication field, bypassing validation and achieving arbitrary OS command injection on the client's host machine. |
