CVE-2026-56547Network attack vector

Device availability loss via unvalidated profile fields

Published Aug 26, 2026 · Updated Aug 26, 2026

Improper input validation in HCL Traveler before 14.5.1.1 allows remote authenticated users to generate profiles with arbitrary identity values. The Apple profile page reflects submitted Logon Name and Mail Address values into an ILNT.mobileconfig file without verifying them against the authenticated user's Domino directory entry. Exploitation requires the authenticated user to install the generated profile, confining the resulting availability impact to that user's device.
