Title
AzuraCast before 0.23.6 Code Injection via Remote Relay Password
Summary
AzuraCast before 0.23.6 contains a code injection vulnerability in the remote relay password field due to incomplete migration from the vulnerable cleanUpString method to toRawString. Attackers with RemoteRelays station permission can inject nested Liquidsoap interpolation syntax to execute arbitrary code in the Liquidsoap process, disclose internal API keys, or disrupt station operation.
