CVE-2024-20769
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 6.5.20 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 · moderate confidenceStored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager versions 6.5.20 and earlier allows attackers to inject malicious JavaScript into form fields. When victims browse to pages containing the affected fields, the embedded scripts execute in their browsers.

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 installed AEM versionAccess the AEM Web Console or check the product version information page (typically at /system/console or through the About Adobe Experience Manager menu option in the top-right help menu)Affected if The version shown is 6.5.20 or earlier, OR it is a 2024.x version earlier than 2024.5
-
Verify the AEM release branchCheck the detailed version string in the About screen - AEM uses two numbering schemes: 6.5.x for the long-term support branch and a year.month format (e.g., 2024.1, 2024.2) for the quarterly release trainAffected if The version is in the 6.5 series at 6.5.20 or below, OR the year-based version is 2024.4 or earlier
-
Determine if form components are in useReview the AEM content structure for pages containing Adaptive Form components, Form fragments, or custom form field components that accept user input and store data in the repositoryAffected if Form components that capture and store user input are present and accessible to unauthenticated or low-privileged users
-
Inspect form field configurations for input validationExamine the form field component policies and their validation settings in AEM Forms or the Core Components configuration editor to see if content filtering is enabledAffected if Form fields lack proper input validation or output encoding configuration, allowing raw HTML/JavaScript to be stored and rendered
You are affected if your AEM installation shows version 6.5.20 or earlier in the 6.5 branch, or any version below 2024.5 in the quarterly release train, AND you have form fields that accept user input without strict validation enabled.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped6.5.212024.5
Upgrade Adobe Experience Manager to version 6.5.21 or later to apply the security patch; audit existing form fields for malicious payloads and implement input validation.
AEM 6.5.21 (or later) / AEM as a Cloud Service 2024.5 (or later)
- Confirm current Adobe Experience Manager version by checking the AEM welcome page or system console
- For AEM 6.5.x on-premises: Upgrade to AEM 6.5.21 or later
- For AEM as a Cloud Service: Ensure the environment is updated to version 2024.5 or later
- After upgrade, verify that the stored XSS vulnerability is resolved by testing form field inputs with malicious script payloads
- Confirm normal application functionality remains intact after the upgrade
