## Description

AzuraCast before 0.23.8 contains a command injection vulnerability in the Liquidsoap config generation for live recording that fails to quote the streamer username in process.run calls. Authenticated station users with Streamers and Profile permissions can set a username containing shell metacharacters and trigger command execution as the Liquidsoap process user when recording closes.

## What to do

- Check your stack: if you ship or depend on AzuraCast, upgrade to a fixed version (0.23.8) per the references below.
