CVE-2026-48265
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 6.5.24, LTS SP1, 2026.04 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this issue by manipulating the DOM environment to execute malicious JavaScript within the context of the victim's browser. Exploitation of this issue requires user interaction in that a victim must visit a crafted webpage. Scope is changed.
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 is affected by a DOM-based Cross-Site Scripting (XSS) vulnerability in versions 6.5.24, LTS SP1, 2026.04 and earlier. The vulnerability allows attackers to manipulate the DOM environment to execute malicious JavaScript within the victim's browser. This is a client-side vulnerability where user interaction (visiting a crafted webpage) is required for exploitation.

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 version through the system information console (typically at /system/console/config or by checking the build info file in the installation directory)Affected if The version is 6.5.24, LTS SP1, 2026.04, or any version earlier than 6.5.25.0 or 2026.5.0
-
Determine if user-supplied content is rendered in the DOMReview application code and templates that accept and render user input (query parameters, form submissions, API responses) in the browser DOM without output encodingAffected if The application renders any user-supplied content directly into the HTML DOM without proper encoding or sanitization
-
Check for client-side rendering componentsAudit JavaScript code that dynamically builds DOM elements from external sources, including AJAX responses, URL parameters, or third-party integrationsAffected if The application uses client-side JavaScript to insert unsanitized data into the DOM (e.g., innerHTML, document.write, or similar methods)
You are affected if your AEM version is 6.5.24, LTS SP1, 2026.04, or any version before 6.5.25.0 or 2026.5.0 AND your application renders untrusted user input directly into the DOM without encoding.

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 · scoped6.5.25.02026.5.0
Apply the vendor-provided patch for Adobe Experience Manager. In the interim, implement Content Security Policy (CSP) headers to mitigate XSS execution and sanitize any user input before DOM manipulation.
AEM 6.5.x → 6.5.25.0+; AEM 2026.x → 2026.5.0+
- Identify the current Adobe Experience Manager version from the system information or AEM welcome page
- Plan the upgrade during a maintenance window following Adobe's standard upgrade procedures
- Upgrade AEM 6.5.x installations to version 6.5.25.0 or later
- Upgrade AEM 2026.x installations to version 2026.5.0 or later
- After upgrade, verify the new version is installed and the application functions correctly
- Test that the DOM-based XSS vulnerability is no longer present by confirming the fix is applied
