# CVE-2025-65719: Open Source Kubectl MCP Server vulnerable to arbitrary code execution via user interaction with crafted HTML page

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.6% , percentile 47: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 47% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes kubectl-mcp-server (npm) < 1.2.0, fixed in 1.2.0 ; kubectl-mcp-server (PyPI) < 1.2.0, fixed in 1.2.0 . Check your lockfile, including transitive dependencies.

## What it is
