CVE-2023-4930Public exploitNetwork attack vector

Private attachment disclosure via directory listing

Published Nov 6, 2023 · Updated Feb 26, 2025

Sensitive data exposure in Front End PM before 11.4.3 allows remote attackers to download private-message attachments via HTTP. The attachment storage directories lack a control that prevents the web server from enumerating their contents. Exploitation requires directory autoindexing to be enabled; exposed listings reveal attachment URLs and permit unauthenticated downloads, without a reported write or service-interruption impact.
