Upgrade tsparticles to version 4.3.1 or later, where this uncaught exception vulnerability is fixed. No other mitigations are indicated.
Description
A vulnerability in tsparticles prior to version 4.3.1 allows an unauthenticated attacker to send a malformed JSON body to the HTTP mode of @tsparticles/mcp-server, causing a SyntaxError that terminates the Node.js process. This results in denial of service by making the MCP service unavailable until manually restarted. The issue is fixed in version 4.3.1.
