CVE-2026-56547: An input reflection vulnerability affects HCL Traveler
The Apple profile generated for the Apple built-in Mail, Calendar and Contacts account to synchronize with HCL Traveler requires the Logon Name and Mail Address to be embedded in them. The values cannot be changed later on, so the Apple profile generation page asks for those values and reflects them back in the generated Apple profile. The Apple profile is not usable without additional information and only allows the attacker to attack their own device, but HCL Traveler could at least check that the values submitted and reflected back in the Apple profile are found in the Domino directory entry for the already authenticated user.

Frequently Asked Questions
Who can exploit this issue?
An attacker needs low-level authenticated access and user interaction. The generated Apple profile requires additional information before it can be used.
What is the practical impact of exploitation?
The issue only enables an attacker to target their own device. The supplied severity vector indicates no confidentiality or integrity impact and a low availability impact.
What validation would reduce the risk during Apple profile generation?
HCL Traveler could verify that the submitted Logon Name and Mail Address match the Domino directory entry for the authenticated user before reflecting those values in the generated profile.
