Medium (5.1). EPSS 0.2% estimated probability of exploitation activity in the next 30 days.
AzuraCast before 0.24.0 contains a CRLF injection vulnerability that allows low-privilege station users to inject playlist entries by embedding CR/LF sequences in mount or remote relay display_name values. Attackers with Station:MountPoints or Station:RemoteRelays permission can inject FileN= and TitleN= lines into the public playlist.pls to redirect guest listeners to attacker-controlled streams under the victim station's name.
