CVE-2026-56547

LOW
Published Aug 26, 2026 Modified Aug 28, 2026 CWE-20 CWE-184

Description

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.
