CVE-2025-64539
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 DOM-based Cross-Site Scripting (XSS) vulnerability that could lead to arbitrary code execution. An attacker could exploit this vulnerability by injecting malicious scripts into a web page that are executed in the context of the victim's browser. A successful attacker can abuse this to achieve session takeover, increasing the confidentiality and integrity impact as high. Exploitation of this issue requires user interaction in that a victim must visit a crafted malicious page.
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 confidenceA DOM-based Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager versions 6.5.23 and earlier allows attackers to inject malicious scripts into web pages. When victims visit crafted malicious pages, the scripts execute in their browser context, enabling arbitrary code execution and session takeover.

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 Welcome page or check the product.xml file in the crx-quickstart folder. The version is typically displayed on the Welcome screen under 'Adobe Experience Manager' or can be retrieved via the JMX console by checking the 'Product Information' MBean.Affected if The installed version is 6.5.23 or earlier, or falls below 6.5.24.0, or is below 2025.12.0, or matches version 6.5 (without a specific patch version).
-
Review custom client-side code for unsafe DOM operationsExamine any custom clientlibs (JavaScript files in /etc/clientlibs or /apps) for usage of innerHTML, outerHTML, document.write, eval(), or similar DOM-manipulation methods that process URL parameters or user-supplied data without sanitization.Affected if Custom JavaScript code processes unsanitized input from URL parameters (such as query strings or hash fragments) and injects it directly into the DOM using unsafe methods.
-
Audit custom AEM components for XSS-prone patternsReview custom AEM components in /apps for JSP or HTL files that render user input or request parameters without proper HTML encoding or contextual escaping.Affected if Custom components accept request parameters and render them directly in the page output without applying XSS protection such as HTL's context-aware escaping or JSTL's escapeXml.
-
Check for Content Security Policy implementationReview the AEM dispatcher configuration or web server (Apache/Nginx) configuration for CSP response headers. Inspect the HTTP responses from the AEM publish instance using browser developer tools or curl to verify if CSP headers are present.Affected if No Content Security Policy (CSP) headers are configured, or CSP headers are permissive and allow inline scripts (unsafe-inline), which would allow DOM-based XSS to execute malicious scripts.
The environment is affected if the AEM version is 6.5.23 or earlier (or below 6.5.24.0 or 2025.12.0) and custom components or client-side code handle user input unsafely in the DOM without CSP mitigation.

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 · scoped6.5.24.02025.12.0
Upgrade Adobe Experience Manager to version 6.5.24 or later. Additionally, implement Content Security Policy (CSP) headers and validate/sanitize all user inputs to mitigate XSS vectors.
AEM 6.5.24.0 (for 6.5.x line) or 2025.12.0 (for continuous release train)
- 1. Identify your current Adobe Experience Manager version by checking the AEM login page footer or system console (Help > About Adobe Experience Manager)
- 2. For AEM 6.5.x on-premise installations: Schedule an upgrade to version 6.5.24.0 or later
- 3. If using AEM cloud services or the continuous release track: Upgrade to 2025.12.0 or later release
- 4. Before upgrading in production, test the upgrade in a staging environment to verify compatibility with custom code and integrations
- 5. After upgrading, validate that the DOM-based XSS vulnerability is remediated by reviewing the AEM security patch notes and confirming the specific CVE is addressed
- 6. Clear browser caches and test the application functionality to ensure the upgrade did not break existing features
