Command execution via unsanitized OAuth endpoint
Published Aug 13, 2025 · Updated Aug 13, 2025
OS command injection in Cherry Studio 1.2.5 through 1.5.1 allows remote attackers to execute commands through a malicious MCP server. The MCP OAuth provider passes an unsanitized server-supplied authorization_endpoint URL to the open function, allowing encoded URL credentials to become an operating-system command. Exploitation requires a victim to add and connect to the attacker's Streamable HTTP MCP server; commands run with the desktop user's privileges.
