Summary
AzuraCast before 0.24.0 contains a CRLF injection vulnerability (CWE-93) in mount and remote relay display_name values. An attacker with the Station:MountPoints or Station:RemoteRelays permission can embed CR/LF sequences to inject FileN= and TitleN= lines into the public playlist.pls. Guest listeners are then redirected to attacker-controlled streams under the victim station's name. CISA's SSVC rates exploitation as none, and the flaw is not in CISA KEV.
