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 6.5.19 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 6.5.19 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability where malicious JavaScript can be injected into form fields. The malicious payload persists in the system and executes in victim users' browsers when they navigate to pages containing the compromised form fields.

MitigationUpgrade Adobe Experience Manager to version 6.5.20 or later to obtain the vendor patch. Additionally, implement input validation and output encoding on form fields as a defense-in-depth measure.

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
    Locate the AEM version information in the product console, system information page, or version.properties file. Common locations include the 'Help > System Information' menu in the AEM author instance or the version manifest file in the installation directory.
    Affected if The installed version is below 6.5.20.0 or below the 2024.03 release (e.g., 6.5.19, 6.5.18, or earlier) - these versions contain the unpatched stored XSS vulnerability in form fields.
  2. Identify form fields accepting user input
    Review all form components or user-generated content fields deployed in AEM that accept and store user input. This includes custom form models, adaptive forms, comment fields, contact forms, or any other data entry points that persist content to the repository.
    Affected if The AEM instance hosts form fields that accept and store user-submitted content without being patched to the fixed version.
  3. Inspect stored form data for malicious payloads
    Query the AEM repository (via CRX/DE or the repository explorer) or examine saved form submissions for suspicious script tags, javascript: URLs, or event handler attributes (onerror, onload, onClick) that may indicate injected XSS payloads.
    Affected if Any stored form field data contains JavaScript code or HTML markup that was injected and persists in the system, indicating the vulnerability has been exploited.
  4. Review content serving endpoints
    Examine how form field data is rendered back to users. Check the output encoding configuration for form components and verify whether data retrieved from the repository is properly escaped before being displayed in pages.
    Affected if Form data is rendered without proper output encoding, which would allow stored XSS payloads to execute in victim browsers.

You are affected if your installed AEM version is below 6.5.20.0 (or below 2024.03) AND your environment uses form fields that accept and store user input, as this combination creates the conditions for the stored XSS to persist and execute.

Upgrade available Upgrade to 6.5.20.0 / 2024.03 or later
Fixed in 6.5.20.02024.03
Interim mitigation

Upgrade Adobe Experience Manager to version 6.5.20 or later to obtain the vendor patch. Additionally, implement input validation and output encoding on form fields as a defense-in-depth measure.

Recommended fix High confidence

AEM 6.5.20.0 (6.5.x line) or AEM 2024.03 (Cloud/2024 release line)

  1. 1. Identify the current Adobe Experience Manager version in your deployment
  2. 2. For AEM 6.5.x deployments: Plan upgrade to version 6.5.20.0 or later
  3. 3. For AEM Cloud/2024 deployments: Plan upgrade to version 2024.03 or later
  4. 4. Schedule maintenance window for the upgrade process
  5. 5. Perform full backup of AEM instance and content repository before upgrade
  6. 6. Execute upgrade following Adobe's official upgrade documentation
  7. 7. After upgrade, verify that the XSS vulnerability is resolved by testing form fields for proper input sanitization
  8. 8. Validate that custom code and integrations remain functional post-upgrade
