CVE-2026-28698Network attack vector

Unauthenticated host and share filesystem disclosure

Published Jul 23, 2026 · Updated Jul 23, 2026

Information exposure in PRONETIQS IntraVUE 3.2.1a14 and earlier allows remote attackers to read the underlying host and share filesystem. CISA and PRONETIQS have not disclosed the vulnerable endpoint or the operation that exposes filesystem content to untrusted requests. Exploitation requires network access but no authentication or user interaction, and the documented consequence is limited to confidentiality loss.
