Technical details

The DownloadTaskEndpoint WebSocket endpoint (/tasks/download/monitor.socket) in goobi-viewer-core versions 24.03 through before 26.05 fails to validate authentication for download requests, accepting them from unauthenticated users. The vulnerability includes an SSRF component where external URLs are not properly validated before downloading. An attacker can exploit this via network access to craft malicious download requests, potentially accessing restricted resources or triggering server-side requests to internal systems.
