CVE-2025-53967

Framelink Figma MCP Server before 0.6.3 allows an unauthenticated remote attacker to execute arbitrary operating system commands via a crafted HTTP POST request with shell metacharacters in input that is used by a fetchWithRetry curl command. The vulnerable endpoint fails to properly sanitize user-supplied input, enabling the attacker to inject malicious commands that are executed with the privileges of the MCP process. Exploitation requires network access to the MCP interface.

Summary		(es) Framelink Figma MCP Server antes de 0.6.3 permite a un atacante remoto no autenticado ejecutar comandos arbitrarios del sistema operativo a través de una solicitud HTTP POST manipulada con metacaracteres de shell en la entrada que es utilizada por un comando curl fetchWithRetry. El endpoint vulnerable no logra sanear adecuadamente la entrada proporcionada por el usuario, permitiendo al atacante inyectar comandos maliciosos que se ejecutan con los privilegios del proceso MCP. La explotación requiere acceso de red a la interfaz MCP.
