Summary
FastlyMCP up to commit 6f3d0b0e654fc51076badc7fa16c03c461f95620 is vulnerable to OS command injection in the fastly_cli Tool function within fastly-mcp.mjs. Manipulating the command argument allows remote command execution. A public exploit exists, and the project has not responded to the issue report.
Risk Assessment
A remote attacker could execute arbitrary commands on the server, potentially leading to full system compromise and data exfiltration.
Recommendation
Immediately stop using FastlyMCP until an official patch is released, or apply temporary mitigations such as restricting access to the tool.
