Sources and claim methodology

Upstream source description

AzuraCast through 0.23.x 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.
