CVE-2023-51464
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 6.5.18 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low-privileged 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 6.5.18 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability. A low-privilege attacker can inject malicious JavaScript into vulnerable form fields, which persists in the system. When other users view pages containing these compromised fields, the injected script executes in their browsers, enabling session hijacking, credential theft, or other client-side attacks.

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 AEM versionAccess the AEM Welcome page or check the product version through the system console (/system/console/bundles or about the system info). Compare the installed version number to the affected range.Affected if The installed version is 6.5.18 or any earlier version (including older 6.x releases)
-
Identify form-based user input areasReview the AEM instance for custom or out-of-the-box forms that accept user-submitted content, such as comment forms, contact forms, user registration forms, or any Adaptive Form components that store data in the repository.Affected if Form fields that accept and store user input exist and are publicly or internally accessible
-
Inspect form submissions for unsanitized contentQuery the AEM content repository (via CRX/DE or the Query Builder) for form submission nodes or user-generated content that may contain script tags or JavaScript event handlers in text fields.Affected if Stored form submissions contain raw HTML, script tags, or JavaScript event attributes (onclick, onload, etc.) without encoding or validation
You are affected if AEM version 6.5.18 or earlier is running AND the system contains forms or user input fields that store unsanitized content in the repository.

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 · scopedUpgrade Adobe Experience Manager to version 6.5.19 or later to receive the security patch. Additionally, implement output encoding and input validation on form fields as a defense-in-depth measure.
Adobe Experience Manager 6.5.19 or later (verify exact fixed version via Adobe security bulletin)
- Check Adobe's official security bulletin (helpx.adobe.com) for CVE-2023-51464 to confirm the exact fixed version
- Identify your current Adobe Experience Manager version in the System Overview or by checking the crx-quickstart folder
- Plan the upgrade during a maintenance window following Adobe's documented upgrade procedure
- Before upgrading, back up your AEM instance including the repository, configuration, and any custom code
- Perform the upgrade in a non-production environment first to validate compatibility
- After upgrading to the fixed release, verify that the vulnerable form fields no longer accept malicious script injections
- Test critical user workflows to ensure the upgrade has not broken existing functionality
