NVD description

tsParticles is a TypeScript library for creating highly customizable particle animations. Prior to 4.3.1, the HTTP mode of @tsparticles/mcp-server calls JSON.parse outside a request-local error boundary in the POST /mcp handler in integrations/mcp-server/src/index.ts. A single unauthenticated malformed JSON body raises a SyntaxError that terminates the Node.js process, leaving the MCP service unavailable until an external supervisor restarts it. This issue is fixed in version 4.3.1.
