Symptoms

• 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.

• This issue affects:
  • R82.10 with Jumbo Hotfix Take 6 or below
  • R82 with Jumbo Hotfix Take 91 or below
  • R81.20 with Jumbo Hotfix Take 127 or below
  • All releases from R81.10 and below
• Spark Firewall is not affected by this issue because it does not support DLP.
• This issue received the ID CVE-2026-48134.
