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 6.5.20 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 6.5.20 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability. Attackers can inject malicious JavaScript into form fields, which persists on the server. When legitimate users browse to pages containing these compromised fields, the malicious script executes in their browsers, potentially stealing session cookies or performing actions on behalf of the victim.

MitigationUpdate AEM to version 6.5.21 or later to obtain the vendor patch. Additionally, implement input validation and output encoding on form fields, and consider applying Content Security Policy (CSP) headers to mitigate XSS execution.

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 installed AEM version
    Navigate to AEM Welcome page or check the product version via the system information console (typically at /system/console/config or by reviewing the manifest file in the crx-quickstart folder)
    Affected if The version is 6.5.20 or earlier, or falls below 2024.5 (for newer release trains)
  2. Identify form endpoints accepting user input
    Review the application's form components and custom form submissions by examining the /apps and /libs directories for form field definitions, or search for JSP/sightly files handling form submissions
    Affected if Forms that accept user input without server-side validation are present and accessible to unauthenticated or low-privileged users
  3. Inspect stored form data for malicious scripts
    Query the JCR (Java Content Repository) using CRXDE Lite or a tool like curl with JMESPath to examine stored form field values in the repository (look under /content or /var for form submission nodes)
    Affected if Any form field entries contain script tags, javascript: URIs, or event handler attributes (onerror, onload, onclick, etc.) embedded in the stored values
  4. Check form field output for unencoded rendering
    Review the Sightly/JSP templates that render form values to verify if output encoding is applied (look for ${formField} vs ${formField @ context='html' or @ context='attribute'} in Sightly templates)
    Affected if Form values are rendered without proper context-aware encoding (html, attribute, or element context)
  5. Review Content Security Policy headers
    Inspect HTTP responses from the AEM instance using browser developer tools or curl to check for CSP headers, or review the Apache Sling dispatcher configuration
    Affected if No CSP headers are configured or CSP is too permissive (allows 'unsafe-inline' or 'unsafe-eval'), which would allow executed scripts to perform actions

The environment is affected if the AEM version is below 6.5.21 or 2024.5, and form fields that accept user input are present without proper output encoding.

Upgrade available Upgrade to 6.5.21 / 2024.5 or later
Fixed in 6.5.212024.5
Interim mitigation

Update AEM to version 6.5.21 or later to obtain the vendor patch. Additionally, implement input validation and output encoding on form fields, and consider applying Content Security Policy (CSP) headers to mitigate XSS execution.

Recommended fix High confidence

Adobe Experience Manager 6.5.21 or 2024.5 (depending on release train)

  1. 1. Identify the current Adobe Experience Manager version by checking /system/console/bundles or the AEM welcome page
  2. 2. For AEM 6.5.x line: Plan upgrade to version 6.5.21 or later
  3. 3. For AEM 2024.x line: Plan upgrade to version 2024.5 or later
  4. 4. Review Adobe's release notes for the target version to understand changes
  5. 5. Create a backup of the current AEM instance and content repository
  6. 6. Test the upgrade in a staging environment before production deployment
  7. 7. Deploy the upgraded version to production
Caveat Security patch releases are typically backward compatible but test thoroughly before production
