CVE-2025-53967 is an OS command-injection vulnerability in Framelink Figma MCP Server versions before 0.6.3. A vulnerable endpoint incorporates insufficiently sanitized, attacker-controlled input into a curl command used by the fetchWithRetry functionality. An unauthenticated remote attacker can submit a crafted HTTP POST request containing shell metacharacters and cause arbitrary operating-system commands to execute with the privileges of the MCP server process.
