CVE-2026-8045
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCWE-611 Improper Restriction of XML External Entity Reference vulnerability exists that could cause information disclosure of server-side file contents when an attacker with a Data Center Expert user account submits crafted XML payloads to SOAP service endpoints.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a CWE-611 XXE (XML External Entity) vulnerability in Data Center Expert's SOAP service endpoints. An authenticated attacker with a Data Center Expert user account can submit crafted XML payloads containing external entity references to read server-side file contents from the underlying system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine Data Center Expert versionLocate and verify the installed version of Schneider Electric Struxureware Data Center Expert in your environmentAffected if The installed version is below 9.1.2
-
Confirm SOAP service is accessibleIdentify whether SOAP service endpoints are exposed and reachable in your Data Center Expert deploymentAffected if SOAP endpoints are accessible to authenticated users
-
Inspect XML parser settingsReview XML parser configuration for the SOAP endpoints to check if external entity processing or DTD processing is enabledAffected if External entities or DTD processing is enabled in the SOAP endpoint XML parsers
You are affected if your Data Center Expert version is below 9.1.2 AND SOAP service endpoints are accessible with external entity processing allowed in their XML parsers.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped9.1.2
Disable XML external entity processing in the SOAP service's XML parser configuration, or implement input validation to reject XML payloads containing DOCTYPE or entity declarations.
Struxureware Data Center Expert 9.1.2
- 1. Back up the current Data Center Expert configuration and database.
- 2. Download Struxureware Data Center Expert version 9.1.2 or later from the Schneider Electric download portal (download.schneider-electric.com).
- 3. Review the upgrade documentation and release notes for version 9.1.2.
- 4. Execute the upgrade following the official installation/upgrade procedure.
- 5. Verify the SOAP service endpoints are functioning correctly after upgrade.
- 6. Confirm the XML external entity restriction is now properly enforced.
