CVE-2026-48280
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.

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 (Help > System Information) or check the version.properties file in the crx-quickstart folder. Alternatively, append /system/console/bundles.json to your AEM instance URL to retrieve version details.Affected if The version displayed is 6.5.24 or earlier, or falls below 6.5.25.0, or is version 2026.04 or earlier (below 2026.5.0).
-
Verify if custom components handle URL parameters or user inputSearch your AEM instance for custom HTL templates, JavaScript files, or Sightly components that directly read URL parameters (request.queryString), cookies, or DOM elements and insert them into the page without using AEM's built-in encoding mechanisms.Affected if Custom code retrieves user-supplied data and inserts it into the DOM using innerHTML, document.write, or similar methods without encoding.
-
Inspect client-side code for unsafe DOM manipulationUse browser developer tools to examine JavaScript files loaded in your AEM pages. Look for patterns like element.innerHTML = userInput or eval(userInput) where userInput originates from URL parameters, referrer headers, or fragment identifiers.Affected if Any JavaScript in your AEM pages directly manipulates the DOM with unsanitized user input derived from the URL hash, query string, or cookies.
-
Review AEMForms or interactive componentsIf AEMForms, Adaptive Forms, or interactive components are deployed, inspect their client-side JavaScript for direct DOM insertion of form field values or workflow data without server-side encoding.Affected if Form components or workflow handlers expose data to the client-side DOM without proper encoding.
Your environment is affected if the installed AEM version is below 6.5.25.0 (for 6.5.x branches) or below 2026.5.0 (for the 2026 release line), AND custom code or components accept user input and render it into the DOM without encoding.

dbcve · scoped6.5.25.02026.5.0
Update to patched AEM versions (after 6.5.24, LTS SP1, 2026.04) and implement Content Security Policy (CSP) headers to mitigate DOM-based XSS execution.
AEM 6.5.25.0 (LTS) or 2026.5.0 (2026 release track)
- 1. Identify the current Adobe Experience Manager version by checking the AEM About page or using the version servlet
- 2. If running AEM 6.5.x LTS, upgrade to version 6.5.25.0 or later
- 3. If running the 2026.x release track, upgrade to version 2026.5.0 or later
- 4. After upgrade, verify the AEM instance is operational and all custom code functions correctly
- 5. Test the fix by ensuring the vulnerable endpoint no longer executes arbitrary JavaScript in the DOM
