CVE-2024-26034
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 XSS vulnerability where malicious JavaScript can be injected into form fields. The malicious payload persists on the server and executes when users view pages containing the 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.
-
Identify Adobe Experience Manager installationLocate AEM instance by accessing common AEM endpoints (such as the AEM Welcome page at /libs/granite/core/content/login.html or the About page at /system/console/about) or check for AEM-related processes and directories on the server.Affected if AEM is installed on the system
-
Determine installed AEM versionAccess the AEM About page (typically at /system/console/about) or use the CRXDE Lite interface to locate version information. The version is displayed in the product version field.Affected if The installed version cannot be determined or is older than the listed versions
-
Compare version against affected rangesIf the version is identified, verify whether it falls below 6.5.20.0 or below 2024.3.0. Both conditions indicate the instance is within the affected range.Affected if Version is below 6.5.20.0 or below 2024.3.0
-
Identify form fields accepting user inputReview AEM forms created using AEM Forms, Adaptive Forms, or custom form components. Check the form field configurations in AEM Forms (accessible via /aem/forms.html or the Forms UI) or inspect the XML/JSON definitions of adaptive form models.Affected if Form fields that accept unvalidated user input exist in the AEM instance
A user is affected if Adobe Experience Manager is installed with a version below 6.5.20.0 or below 2024.3.0 AND the instance contains form fields where malicious JavaScript could be injected and stored.

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
Upgrade Adobe Experience Manager to a version newer than 6.5.19 or apply the relevant security patch. Input validation and output encoding should also be implemented on form fields as a defense-in-depth measure.
AEM 6.5.20.0 (for 6.5.x line) or AEM 2024.3.0 (for 2024+ releases)
- Review the Adobe Experience Manager 6.5.20.0 or 2024.3.0 release notes for changes, fixes, and any breaking changes relevant to your implementation
- Perform a complete backup of your AEM repository (crx-quickstart), database, and any custom code
- Create a staging or development environment identical to production
- Test the upgrade in the staging environment first to identify any compatibility issues with custom code or third-party integrations
- Upgrade AEM to version 6.5.20.0 (for 6.5.x installations) or to version 2024.3.0 (for Cloud Service or newer release lines)
- After upgrade, verify all custom applications, workflows, and integrations function correctly
- Deploy the validated upgrade to production
