CVE-2024-26124
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 6.5.19 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 confidenceAdobe Experience Manager versions 6.5.19 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability in form fields. Attackers can inject malicious JavaScript into vulnerable form inputs, which persists in the system and executes when legitimate users browse to pages containing those affected fields.

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 AEM version installedLog in to AEM as administrator and navigate to Help > System Information, or append /system/console/bundles to your AEM URL. Locate the Product Version field.Affected if The version shown is below 6.5.20.0 or below 2024.3.0 (for cloud/2024 releases)
-
Identify custom form componentsNavigate to the CRXDE Lite (append /crx/de to your AEM URL) and search under /apps for nodes containing 'form' in the name, particularly under /apps/<your-project>/components. Look for form field components that accept user input.Affected if Custom form components exist in the /apps directory that handle user input without output encoding
-
Review form field input validationExamine the JSP, HTL, or Java code for form field components. Check if the code uses proper output encoding (such as HTL escaping, or XSS API like XSSAPI.encodeForHTML) when rendering form field values back to the user.Affected if Form components render submitted values back to users without encoding (no XSSAPI calls or HTL contextual encoding)
-
Inspect content fragments using formsCheck if AEM Forms or Adaptive Forms are used. Review the form models under /conf or /apps for how submitted data gets stored and displayed in content fragments or experience fragments.Affected if Forms store and display user-submitted content without sanitization
Your environment is affected if AEM version is below 6.5.20.0 (or below 2024.3.0 for cloud) AND custom or out-of-the-box form fields that accept user input are in use and render that input back without proper output encoding.

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 · scoped6.5.20.02024.3.0
Update Adobe Experience Manager to version 6.5.20 or later to obtain the security patch. Additionally, implement output encoding and input validation on form fields as a defense-in-depth measure.
AEM 6.5.20.0+ (6.5.x branch) or AEM 2024.3.0+ (2024 release train)
- 1. Back up the current Adobe Experience Manager instance and associated data
- 2. Download Adobe Experience Manager version 6.5.20.0 or later from the official Adobe distribution portal
- 3. Follow Adobe's official upgrade documentation to install the update
- 4. After upgrade, verify the fix by testing form fields that were previously vulnerable to stored XSS
- 5. Confirm that malicious scripts can no longer be stored and executed in form fields
