CVE-2026-59176: Functype MCP Server Arbitrary Code Execution

The functype-mcp-server prior to version 1.4.4 contains an arbitrary code execution vulnerability in the `set_functype_version` MCP tool that accepts unconstrained version strings and interpolates them into package installation commands. An attacker or AI assistant can exploit this to install malicious packages and execute arbitrary code with the server's privileges.

npm worm hijacked GitHub accounts, armed 42 repos with hidden payload

JFrog found a Miasma-family npm worm, dubbed 'testmetest', had secretly armed 42 real GitHub repositories from 11 owners since July, planting execution hooks for AI coding assistants like Claude, Gemini, Cursor and VS Code and using oversized polymorphic payloads to evade GitHub and scanner detection. The malware steals credentials, modifies repos and CI configs, self-replicates, and deploys a wiper that deletes the victim's home directory if the stolen GitHub token is revoked.
