Unauthenticated file disclosure via unchecked download path

Published Jun 15, 2026 · Updated Jun 15, 2026

Path traversal in HB Audio Gallery Lite 1.0.0 allows remote attackers to read arbitrary server files through a crafted download request. The gallery/audio-download.php endpoint accepts file_path as the filesystem path while applying basename only to the response filename. No authentication is required, and traversal sequences can escape the plugin directory to disclose configuration files such as wp-config.php.
