CVE-2024-52842
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 6.5.21 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 confidenceAdobe Experience Manager versions 6.5.21 and earlier contain a stored Cross-Site Scripting vulnerability in form fields. Attackers can inject malicious JavaScript payloads into form inputs that persist on the page, which then execute in victim browsers when they view the affected content.

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.
-
Check installed AEM versionLocate the AEM version number in the product UI (Help > About Adobe Experience Manager) or check the version.properties file in the crx-quickstart folderAffected if The version is below 6.5.22.0 or below 2024.11.0
-
Identify if AEM Forms is enabledCheck if the AEM Forms addon is installed by navigating to Tools > Forms in the AEM console or checking for /aem/forms in the URLAffected if AEM Forms module is present and active
-
Verify form field input validation settingsReview form field configurations in the Forms editor - check if Input Validation is configured for text fields that accept user inputAffected if Form fields lack input validation rules or allow raw HTML/script input
-
Inspect stored form data for unsanitized contentExamine form submissions in the AEM repository (CRXDE Lite under /content/forms/af) or form data model outputs for any script tags or JavaScript event handlersAffected if Form data contains unencoded script tags or event handler attributes like onerror, onload, onclick
-
Review output encoding on form renderingCheck the form template or adaptive form fragment code to verify if HTL/Sightly encoding is applied to user-submitted values when renderedAffected if User input from forms is rendered without proper HTML encoding or output escaping
A user is affected if their AEM version is below 6.5.22.0 or below 2024.11.0 AND they have AEM Forms enabled with form fields that accept user input without validation or encoding.
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 · scoped6.5.22.02024.11.0
Upgrade to AEM 6.5.22 or later. Additionally, implement output encoding and input validation on form fields to prevent XSS injection.
Adobe Experience Manager 6.5.22.0 (6.5.x line) or 2024.11.0 (2024 release line)
- 1. Identify the current Adobe Experience Manager version in use
- 2. For AEM 6.5.x line: Upgrade to version 6.5.22.0 or later
- 3. For AEM as a Cloud Service / 2024 releases: Upgrade to version 2024.11.0 or later
- 4. After upgrade, verify the XSS fix is applied by testing form field inputs with script tags
- 5. Confirm that stored scripts are not executed when form pages are rendered
