{"id":"CVE-2026-100857","summary":"AzuraCast before 0.23.4 Remote Code Execution via Liquidsoap string interpolation","details":"AzuraCast before 0.23.4 contains a code injection vulnerability in the ConfigWriter::cleanUpString() method that fails to sanitize Liquidsoap string interpolation sequences, allowing authenticated users with Media or Profile permissions to inject arbitrary Liquidsoap code into station configuration. Attackers can inject #{process.run()} expressions into playlist URLs or station metadata fields that execute shell commands as the azuracast user when the station restarts.","aliases":["GHSA-93fx-5qgc-wr38"],"modified":"2026-09-28T03:48:31.990469355Z","published":"2026-09-27T01:28:48.450Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-94"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100857.json"},"references":[{"type":"ADVISORY","url":"https://github.com/AzuraCast/AzuraCast/security/advisories/GHSA-93fx-5qgc-wr38"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100857.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100857"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/azuracast-before-0.23.4-remote-code-execution-via-liquidsoap-string-interpolation"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/azuracast/azuracast","events":[{"introduced":"0"},{"fixed":"cf9e2409e26038e47486d413355b5703145c05c0"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.23.4"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["0.23.3","0.23.2","0.23.1","0.23.0","0.22.1","0.22.0","0.21.0","0.20.4","0.20.3","0.20.2","0.20.1","0.20.0","0.19.7","0.19.6","0.19.5","0.19.4","0.19.3","0.19.2","0.19.1","0.19.0","0.18.5","0.18.3","0.18.2","0.18.1","0.18.0","0.17.7","0.17.6","0.17.5","0.17.4","0.17.3","0.17.2","0.17.1","0.17.0","0.16.1","0.16.0","0.15.2","0.15.1","0.15.0","0.14.1","0.10.2","0.10.1","0.10.0","0.9.9","0.9.8.1","0.9.8","0.9.7.1","0.9.7","0.9.6.5","0.9.6.2","0.9.6.1","0.9.6","0.9.5.1","0.9.5","0.9.4.2","0.9.4.1","0.9.4","0.9.3","0.9.2","0.9.1","0.9.0","0.8.0","0.6.0","0.5.0","0.3.3","0.3.2","0.3.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-100857.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
