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 · unedited
AEM Forms SP6 add-on for AEM 6.5.6.0 and Forms add-on package for AEM 6.4 Service Pack 8 Cumulative Fix Pack 2 (6.4.8.2) have a blind Server-Side Request Forgery (SSRF) vulnerability. This vulnerability could be exploited by an unauthenticated attacker to gather information about internal systems that reside on the same network.

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 confidence

A blind Server-Side Request Forgery (SSRF) vulnerability in Adobe Experience Manager (AEM) Forms add-on packages (6.5.6.0 and 6.4.8.2) allows unauthenticated attackers to make the AEM server initiate requests to internal systems, enabling reconnaissance of internal infrastructure without receiving full HTTP responses.

MitigationApply the Adobe security patch for the affected AEM Forms versions. Additionally, implement network segmentation and egress filtering to restrict outbound connections from the AEM server to internal resources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check AEM Forms add-on package version
    Navigate to the AEM Package Manager at /crx/packmgr/index.jsp or use the Felix console at /system/console/bundles to locate installed AEM Forms packages. Look for packages named similar to 'aem-forms' or 'forms-compatibility' and note their exact version numbers.
    Affected if The installed Forms package version is exactly 6.4.8.2 or exactly 6.5.6.0
  2. Verify AEM core version
    Access the AEM system information at /system/console/bundles or check the version.properties file in the crx-quickstart directory. Note the AEM core version (6.4 or 6.5).
    Affected if AEM core is version 6.4 or 6.5 and the corresponding Forms add-on at the affected versions is installed
  3. Confirm Forms feature is enabled
    Check if the AEM Forms bundle is in an active state by accessing /system/console/bundles and searching for 'com.adobe.forms' or 'Forms' related bundles. Verify the bundle status is Active.
    Affected if The Forms bundles are loaded and active, making the SSRF attack surface accessible
  4. Check for external network exposure
    Review the AEM server's network configuration to determine if it has outbound network access. This can be verified by reviewing firewall rules, security groups, or network configuration that allows the AEM server to initiate outbound HTTP connections.
    Affected if The AEM server has outbound network access, which would allow the SSRF to reach internal infrastructure

You are affected if your AEM Forms add-on package is exactly version 6.4.8.2 or 6.5.6.0 and the Forms bundles are active, enabling unauthenticated attackers to trigger blind SSRF requests from your server.
