Security readout for executives and security teams
Plain-English summary
CVE-2026-27776 affects the IM-LogicDesigner module in intra-mart Accel Platform. If that module is deployed, an administrator importing a crafted file could trigger arbitrary code execution. This is high business risk for organizations using affected versions because compromise could impact confidentiality, integrity, and availability of the platform.
Executive priority
Prioritize assessment if intra-mart Accel Platform supports critical business workflows or contains sensitive data. The required administrative privilege lowers likelihood, but successful exploitation could allow arbitrary code execution on the platform. Treat this as a high-priority validation and vendor-guidance tracking item.
Technical view
The issue is insecure deserialization, CWE-502, in IM-LogicDesigner. Affected versions are intra-mart Accel Platform 2017 Spring (8.0.4) through 2025 Autumn (8.0.27). CVSS 4.0 is 8.6 high, with network attack vector, low complexity, high privileges required, and high impact to the vulnerable system.
Likely exposure
Exposure is limited to systems running affected intra-mart Accel Platform versions with IM-LogicDesigner deployed. The described attack requires administrative privilege and import of a crafted file, reducing broad internet-scale risk but keeping risk serious for privileged-account compromise scenarios.
Exploitation context
The provided sources do not indicate active exploitation, and the CVE is not listed as KEV. Exploitation depends on an administrative user importing a crafted file into a deployed IM-LogicDesigner environment. No public exploit details are included in the provided source bundle.
Researcher notes
Evidence is sufficient for affected product, version range, prerequisite module, privilege requirement, weakness class, and CVSS. The provided sources do not name a specific fixed version, workaround, or observed exploitation. Avoid assuming internet-exploitable status without confirming deployment and administrative workflow exposure.
Mitigation direction
- Check NTT DATA INTRAMART and JVN advisories for official update or mitigation instructions.
- Confirm whether IM-LogicDesigner is required; evaluate disabling or undeploying it if unnecessary.
- Restrict administrative access to trusted users and hardened administrative workstations.
- Control and review files imported by administrators into IM-LogicDesigner.
- Monitor vendor guidance for patches, configuration changes, or compensating controls.
Validation and detection
- Inventory intra-mart Accel Platform versions across production and non-production systems.
- Identify systems from 2017 Spring (8.0.4) through 2025 Autumn (8.0.27).
- Confirm whether IM-LogicDesigner is deployed on each affected system.
- Review administrative import activity for unexpected or untrusted files.
- Track vendor and JVN advisories for remediation status updates.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
