AzuraCast before 0.23.4 contains a code injection vulnerability in the ConfigWriter::cleanUpString() method that fails to sanitize Liquidsoap string… (CVE-2026-100857)
AzuraCast versions prior to 0.23.4 have a code injection vulnerability in the ConfigWriter::cleanUpString() method. This flaw allows authenticated users with Media or Profile permissions to inject arbitrary Liquidsoap code via unsanitized string interpolation sequences. Exploitation can lead to execution of shell commands as the azuracast user when the station restarts.
AI Analysis
Technical Summary
AzuraCast before version 0.23.4 contains a code injection vulnerability (CVE-2026-100857) in the ConfigWriter::cleanUpString() method. The method fails to properly sanitize Liquidsoap string interpolation sequences, enabling authenticated users with Media or Profile permissions to inject arbitrary Liquidsoap code into station configuration fields such as playlist URLs or station metadata. Injected expressions like #{process.run()} can execute shell commands with the privileges of the azuracast user upon station restart. The vulnerability has a CVSS 3.1 score of 8.0, indicating high severity.
Potential Impact
Successful exploitation allows authenticated users with limited permissions to execute arbitrary shell commands on the server running AzuraCast, potentially leading to full compromise of the application environment. This impacts confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
A fix is available in AzuraCast version 0.23.4. Users should upgrade to version 0.23.4 or later to remediate this vulnerability. No other mitigation guidance is provided by the vendor advisory.
