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
Adobe Experience Manager versions 6.5.21 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.

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

Adobe Experience Manager versions 6.5.21 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability in form fields. Attackers can inject malicious JavaScript that persists in the system and executes when users view pages containing the affected fields.

MitigationUpdate Adobe Experience Manager to version 6.5.22 or later to patch the vulnerability. Alternatively, implement input validation and output encoding on form fields, or deploy a WAF rule to filter malicious scripts.

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 Adobe Experience Manager version
    Access the AEM console and navigate to Help > About Adobe Experience Manager, or check the version.properties file in the crx-quickstart folder. Alternatively, query the version endpoint at /system/console/bundles or check the AEM SDK version.
    Affected if The installed version is earlier than 6.5.22.0 or earlier than 2024.11.0, placing it within the affected range.
  2. Identify deployed form components
    Review the AEM content structure under /content or /apps for pages using Adaptive Form components (core form components), Foundation form components, or custom form implementations. Use the AEM search or Site Admin to locate pages containing form elements.
    Affected if The AEM instance hosts pages or templates that include form fields where user input is collected and stored.
  3. Examine form field input validation configuration
    Open the form field component dialog in AEM Forms or check the XML configuration of Adaptive Forms under /content/forms/af. Inspect the validation settings for each form field to determine if input validation and constraints are properly configured.
    Affected if Form fields lack input validation rules, pattern constraints, or allow unrestricted text input that could accept malicious scripts.
  4. Review output encoding settings for form components
    Check the form container or individual field component properties in the AEM edit dialog. Verify the settings under the HTML Property Mapping or the Display Text configuration to confirm output encoding is enabled for user-submitted content.
    Affected if Output encoding is disabled or not explicitly configured on form fields, allowing stored scripts to render unescaped in the browser.

The environment is affected if the installed AEM version is below 6.5.22.0 or below 2024.11.0 AND the system uses form fields that accept user input without proper input validation or output encoding.

Recommended fix High confidence

Adobe Experience Manager 6.5.22.0 or 2024.11.0 and later

  1. Backup the Adobe Experience Manager instance and its data before proceeding with any upgrade
  2. Review Adobe's official upgrade documentation and release notes for version 6.5.22.0 or 2024.11.0 to understand the upgrade process
  3. Test the upgrade in a non-production/staging environment first to ensure compatibility with custom code and configurations
  4. Stop the AEM instance and any related services
  5. Perform the upgrade to AEM 6.5.22.0 (for 6.x customers) or 2024.11.0 (for Cloud Service customers) following Adobe's documented upgrade procedure
  6. After upgrade, verify that the form fields mentioned in the vulnerability are no longer susceptible to XSS injection
  7. Restart the AEM instance and validate all workflows and integrations are functioning correctly
Caveat Review Adobe release notes for any deprecation notices or configuration changes that may affect custom components
