CVE-2026-27225
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 6.5.23 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 · high confidenceAdobe Experience Manager versions 6.5.23 and earlier contain a stored (persistent) Cross-Site Scripting vulnerability in form fields. A low-privileged attacker can inject malicious JavaScript payloads into form fields that persist on the page, executing 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.
-
Identify installed AEM versionAccess the AEM Web Console (System > System Information) or check the version.properties file in the crx-quickstart directory to determine the exact installed version of Adobe Experience Manager.Affected if The installed version is 6.5.x where x is 23 or lower, or the version is earlier than 6.5.24.0, or earlier than 2026.2.0
-
Review custom form field configurationsNavigate to the Forms section in AEM and inspect custom form field components that accept user input and persist data. Check each form field component for input validation settings in the component dialog.Affected if Form fields exist without proper server-side input validation configured, allowing unfiltered HTML or JavaScript to be saved to the repository
-
Audit stored content for malicious payloadsSearch the AEM content repository (via CRXDE Lite or Content Explorer) for common XSS payloads in form field content nodes, looking for patterns like script tags, javascript: protocols, or event handler attributes.Affected if Malicious JavaScript payloads are found persisted in form field content nodes in the repository
A user is affected if they are running Adobe Experience Manager version 6.5.23 or earlier, or version 6.5 without the 6.5.24.0 patch, or any version earlier than 2026.2.0, and have form fields that accept and persist user input without adequate server-side validation.
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 · scoped6.5.24.02026.2.0
Update Adobe Experience Manager to a patched version beyond 6.5.23. Additionally, implement robust server-side input validation and output encoding for all form fields to prevent XSS injection.
AEM 6.5.24.0 or later; AEM as a Cloud Service 2026.2.0 or later
- Back up the current Adobe Experience Manager instance and content repository
- Upgrade AEM 6.5 on-premises to version 6.5.24.0 or later
- If using AEM as a Cloud Service, upgrade to version 2026.2.0 or later
- After upgrade, clear browser cache and test the previously vulnerable form fields to confirm the XSS vulnerability is remediated
- Verify that the AEM upgrade was successful by checking the version in About Adobe Experience Manager
