CVE-2024-43726
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 · moderate confidenceAdobe Experience Manager versions 6.5.21 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability where malicious JavaScript can be injected into vulnerable form fields. The malicious payload persists on the server and executes in victim browsers when they navigate to pages containing the compromised form 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.
-
Determine your Adobe Experience Manager versionAccess the AEM Welcome page or check the product version information in the system console. Compare the installed version number against the affected ranges: versions below 6.5.22.0 or versions below 2024.11.0 are vulnerable.Affected if The installed AEM version is 6.5.21 or earlier, or the version is below 2024.11.0.
-
Identify active forms that accept user inputReview the AEM instance for any form components or custom form implementations that store user-submitted data. Check the Forms section in AEM Assets or any custom form workflows.Affected if Forms that accept and store user input are present in the environment.
-
Inspect stored form data for suspicious scriptsQuery the repository or database where form submissions are stored. Look for HTML script tags, javascript: URIs, or encoded script payloads within form field values.Affected if Form submission records contain unescaped JavaScript code or script tags in any input fields.
-
Review form field input validation settingsExamine the form component configurations in AEM to determine whether input validation and output encoding are enabled for form fields.Affected if Form fields lack input validation rules or output encoding is not configured.
You are affected if your AEM version is below 6.5.22.0 or below 2024.11.0 AND your environment contains forms that accept user input without proper validation.

dbcve · scoped6.5.22.02024.11.0
Upgrade to Adobe Experience Manager version 6.5.22 or later to receive the security patch. Implement input validation and output encoding on form fields as a defense-in-depth measure while planning the upgrade.
AEM 6.5.22.0 or AEM 2024.11.0 (depending on release line in use)
- Identify the current Adobe Experience Manager version in use
- For AEM 6.5.x line: Plan upgrade to version 6.5.22.0 or later
- For AEM 2024.x line: Plan upgrade to version 2024.11.0 or later
- Create a full backup of the AEM instance before upgrading
- Test the upgrade in a non-production environment first
- Perform the upgrade following Adobe's official documentation
- After upgrade, verify the form fields that were previously vulnerable no longer allow script injection
- Confirm the new version is running by checking the AEM About page
