CVE-2019-8086
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 · uneditedAdobe Experience Manager versions 6.5, 6.4, 6.3 and 6.2 have a xml external entity injection vulnerability. Successful exploitation could lead to sensitive information disclosure.
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 confidenceAdobe Experience Manager versions 6.2 through 6.5 contain an XML External Entity (XXE) injection vulnerability. This occurs when the AEM XML parser processes malicious XML input containing external entity references, allowing attackers to read internal files, perform SSRF attacks, or cause denial of service. The CVSS 7.5 score indicates high exploitability with network-based attacks and significant impact on confidentiality.

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 AEM versionAccess the AEM Welcome page and locate the version information, or query the AEM system information endpoint (e.g., /system/console/status-productinfo or /crx/packmgr/service.jsp?cmd=ls), or check the manifest file in the AEM installation directoryAffected if The installed version is 6.2, 6.3, 6.4, or 6.5 exactly
-
Locate XML ingestion pointsReview AEM workflows, custom components, or integrations that accept XML input submissions. Check the /etc/replication or /var/import directories, and search for custom servlets or endpoints that process XML using javax.xml.parsers or org.xml.sax packagesAffected if XML processing functionality exists and is accessible to network attackers
-
Identify exposed XML endpointsReview dispatcher configurations and published endpoints for any web services, API endpoints, or import handlers that accept XML payloads. Check AEM exposed REST services under /bin or /services pathsAffected if Any publicly accessible endpoint accepts and parses XML content
-
Check XML parser configurationInspect the AEM startup scripts, sling.properties, or custom OSGi configurations for XML parser settings. Look for javax.xml.parsers settings and whether external entity processing has been explicitly disabledAffected if The XML parser is configured to allow external entity processing (default vulnerable state)
-
Review recent XML-based importsCheck AEM audit logs (audit.log) and request logs for XML upload or import patterns, and examine any third-party integrations that feed XML to AEMAffected if XML imports are actively being used in the environment
You are affected if your AEM version is exactly 6.2, 6.3, 6.4, or 6.5 AND you have XML processing endpoints accessible to untrusted input sources.

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 dataUpgrade AEM to the vendor-provided patched version or apply the relevant security hotfix. Additionally, configure XML parsers to disable external entity processing as a defense-in-depth measure.
