CVE-2026-48134: SQL injection issue in UserCheck Portal when DLP Software Blade is active

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.

Security readout for executives and security teams

Plain-English summary

This flaw affects Check Point Quantum Security Gateway when DLP is active. If the UserCheck Portal Ask page is reachable, an unauthenticated attacker may disrupt stored DLP/UserCheck incident records or pending approval handling. The rating is medium, but business impact depends heavily on portal exposure to untrusted networks.

Executive priority

Treat this as a near-term perimeter exposure review, not an emergency, unless UserCheck is exposed externally. Prioritize affected gateways with DLP active and any untrusted-network access to the portal.

Technical view

CVE-2026-48134 is a CWE-89 SQL injection issue in the UserCheck Web Portal UserChoice flow. It has CVSS 3.1 score 5.6 with network access, high attack complexity, no privileges, and low confidentiality, integrity, and availability impact. Affected versions include listed R82.10, R82, R81.20 hotfix levels and R81.10 or below.

Likely exposure

Exposure is most likely where affected Check Point Quantum Security Gateway versions run the DLP Software Blade and expose the UserCheck Ask page. Exposure is reduced when the UserCheck Portal is not reachable from untrusted networks.

Exploitation context

The source bundle does not report active exploitation, and this CVE is not listed as KEV. The described attack requires access to the UserCheck Ask page and specific conditions, reflected by high attack complexity in the CVSS vector.

Researcher notes

Evidence supports SQL injection risk in the UserChoice flow, but the public bundle does not provide exploit details, proof of active exploitation, or a named fixed build. Avoid assuming broader Check Point products are affected.

Mitigation direction

  • Review Check Point SK184983 for fixed release or Jumbo Hotfix guidance.
  • Restrict UserCheck Portal access to trusted networks only.
  • Inventory gateways running affected versions and DLP Software Blade.
  • Limit external reachability of the UserCheck Ask page.
  • Monitor Check Point guidance for updated remediation details.

Validation and detection

  • Check gateway versions and Jumbo Hotfix Take levels against the affected list.
  • Confirm whether the DLP Software Blade is active.
  • Test whether UserCheck Ask is reachable from untrusted networks.
  • Review DLP/UserCheck incident records for unexpected loss or approval anomalies.
  • Track vendor advisory updates for fixed-version confirmation.
