Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

AzuraCast versions before 0.23.4 are vulnerable: the config writer does not sanitize Liquidsoap string interpolation sequences in station metadata and playlist URL fields, so they can carry arbitrary Liquidsoap code into the generated configuration. An attacker needs an authenticated account with station-level Media or Profile permission; when the station is later restarted and Liquidsoap parses the config, the injected code can run shell commands on the server as the azuracast user. Upgrade to AzuraCast 0.23.4, which is the fixed version listed.
