Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Open Source Kubectl MCP Server package, published on npm and PyPI as kubectl-mcp-server, is affected in versions before 1.2.0; the source specifically names version 1.1.1. An attacker can execute arbitrary code on a victim's system if the victim interacts with a crafted HTML page. The source gives few details beyond this, and the fix is 1.2.0, so users should upgrade both packages to version 1.2.0 or later.
