CVE-2026-48134 When the DLP is active, the UserCheck Web Portal contains an input-handling issue in the UserChoice flow
Description
When the DLP is active, the UserCheck Web Portal contains an input-handling issue in the UserChoice flow. Under specific conditions, an attacker who can access the UserCheck Ask page could attempt to manipulate the Security Gateway's stored DLP/UserCheck incident information. This could lead to disruptions such as loss of stored incident entries, incorrect handling of pending approvals, or resource impact if the issue is abused repeatedly. Exposure is reduced if the UserCheck Portal is not accessible from untrusted networks.
