Cross-account contact disclosure via missing ownership check
Published Nov 20, 2025 · Updated Nov 20, 2025
Information disclosure in Revive Adserver 5.5.2 and 6.0.1 and earlier allows remote authenticated users to view other users' contact details. UserAccess::process accepted a target user ID without checking whether that user belonged to the caller's account, exposing the target's contact name and email address. Any non-administrator account could cross account boundaries; the consequence is limited to disclosure of those contact fields.
