{"id":"CVE-2026-42605","summary":"AzuraCast: Path Traversal in `currentDirectory` Parameter Enables Remote Code Execution via Media Upload","details":"AzuraCast is a self-hosted, all-in-one web radio management suite. Prior to version 0.23.6, the currentDirectory request parameter in the Flow.js media upload endpoint (POST /api/station/{station_id}/files/upload) is not sanitized for path traversal sequences. When combined with a local filesystem storage backend (the default), an authenticated user with media management permissions can write arbitrary files outside the station's media storage directory, achieving remote code execution by writing a PHP webshell to the web root. This issue has been patched in version 0.23.6.","aliases":["GHSA-vp2f-cqqp-478j"],"modified":"2026-07-08T08:13:26.634751616Z","published":"2026-05-09T19:44:05.893Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42605.json"},"references":[{"type":"WEB","url":"https://github.com/AzuraCast/AzuraCast/releases/tag/0.23.6"},{"type":"ADVISORY","url":"https://github.com/AzuraCast/AzuraCast/security/advisories/GHSA-vp2f-cqqp-478j"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42605.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42605"},{"type":"FIX","url":"https://github.com/AzuraCast/AzuraCast/commit/18c793b4427eb49e67a2fea99a89f1c9d9dd808d"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/azuracast/azuracast","events":[{"introduced":"0"},{"fixed":"52c8050e3524e0f9867cb319eb87c7e3f3dc11f8"},{"fixed":"18c793b4427eb49e67a2fea99a89f1c9d9dd808d"}],"database_specific":{"cpe":"cpe:2.3:a:azuracast:azuracast:*:*:*:*:*:*:*:*","source":["CPE_RANGE","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"0.23.6"}]}}],"versions":["0.23.5","0.23.4","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-2026-42605.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
