CVE-2024-0601Public exploitNetwork attack vector

Authenticated file disclosure via unrestricted attachment URL

Published Jan 16, 2024 · Updated Jun 17, 2025

Server-side request forgery in Austin 1.0 allows remote authenticated users to read server files through crafted email templates. The getRemoteUrl2File method passes an unrestricted attachment URL from an email template to java.net.URL.openStream, then attaches the fetched bytes. Template-management access and a test send are required; a file URI can disclose readable local files by emailing them as attachments.
