Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via the ConfigWriter::cleanUpString process. An attacker can execute arbitrary shell commands by injecting specially crafted Liquidsoap string interpolation sequences into playlist URLs or station metadata fields, which are processed when the station restarts. This is only exploitable if the attacker is an authenticated user with Media or Profile permissions.
