CVE-2026-1567
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 · uneditedIBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 An XML External Entity (XXE) vulnerability in IBM InfoSphere Information Server could allow attackers to retrieve sensitive information from the server.
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 confidenceAn XML External Entity (XXE) vulnerability in IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6 allows attackers to retrieve sensitive information from the server through malicious XML input exploiting external entity processing.

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.
-
Identify the installed IBM InfoSphere Information Server versionUse the version command or check the installation directory. Common methods include: running 'cd /opt/IBM/InformationServer/Version' and executing version info scripts, or checking the 'Version.xml' file in the installation directory. Alternatively, use the IBM InfoSphere Administration Console to view the installed version.Affected if The installed version is 11.7.0.0 through 11.7.1.6 inclusive (versions 11.7, 11.7.0.1, 11.7.1.0, 11.7.1.1, etc.)
-
Confirm XML parsing functionality is in useReview active DataStage jobs, IBM DataStage XML stages, or any custom transformations that process XML input files or streams. Check job logs and scheduler for XML-related job executions. Inspect the IBM InfoSphere metadata repository for XML-enabled data sources.Affected if XML parsing stages, XML transformers, or any components that process XML documents are actively configured or have been recently executed.
-
Inspect XML parser configuration for external entity settingsLocate XML parser configuration files within the IBM InfoSphere Information Server installation. Common locations include: the 'ASBNode' configuration directory, XML processing service configs, or DataStage job parameter files. Look for settings such as 'externalEntity', 'dtdProcessing', or 'entityExpansion' and verify whether they allow external entity resolution.Affected if The XML parser configuration explicitly enables or permits external entity processing (for example, settings that allow DTDs or external entity references in parsed XML documents).
You are affected if IBM InfoSphere Information Server version is 11.7.0.0 through 11.7.1.6 AND XML processing with external entity support is enabled in your configuration.
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.
From vendor dataApply the vendor patch to resolve the XXE vulnerability or disable external entity processing in the XML parser configuration as a compensating control.
