CVE-2026-56547
LowCVSS 3.5Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
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. The values cannot be changed later, and the generation page reflects them back. The profile is not usable without additional info and only allows the attacker to attack their own device, but HCL Traveler could at least check that the values are found in the Domino directory entry for the authenticated user.
Risk Assessment
The vulnerability allows an attacker to manipulate their own profile, but poses no direct threat to other users. However, lack of validation may lead to misconfiguration.
Recommendation
Apply vendor patches or implement validation of Apple profile values against the Domino directory.

Original NVD description (English source)
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.
