What is CVE-2026-42605?

AzuraCast, a self-hosted web radio management suite, has a vulnerability affecting versions before 0.23.6. The 'currentDirectory' request parameter in the media upload endpoint is not sanitized for path traversal sequences. An authenticated user with media management permissions can exploit this flaw when using the default local filesystem storage backend, allowing them to write arbitrary files outside the designated media storage directory. This can lead to remote code execution by writing a PHP web shell to the web root. Users are strongly advised to upgrade to version 0.23.6 or later to mitigate this risk.

Affected Version(s)

AzuraCast < 0.23.6
