Cursor is a code editor built for programming with AI. In versions 1.17 through 1.2, there is a UI information disclosur

Cursor is a code editor built for programming with AI. In versions 1.17 through 1.2, there is a UI information disclosure vulnerability in Cursor's MCP (Model Context Protocol) deeplink handler, allowing attackers to execute 2-click arbitrary system commands through social engineering attacks. When users click malicious cursor://anysphere.cursor-deeplink/mcp/install links, the installation dialog does not show the arguments being passed to the command being run.

If a user clicks a malicious deeplink, then examines the installation dialog and clicks through, the full command including the arguments will be executed on the machine. This is fixed in version 1.3.
