CVE-2025-47062: Adobe Experience Manager XSS Vulnerability

CVE-2025-47062 Overview

Adobe Experience Manager (AEM) versions 6.5.22 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability [CWE-79]. A low-privileged authenticated attacker can inject malicious JavaScript into vulnerable form fields. The payload executes in a victim's browser when they visit the affected page. The vulnerability affects both on-premises AEM installations and AEM Cloud Service deployments.

Critical Impact
An authenticated attacker with low privileges can inject persistent JavaScript into form fields, leading to session hijacking, credential theft, or unauthorized actions performed in the context of victim users who load the affected content.

Affected Products

Adobe Experience Manager on-premises versions 6.5.22 and earlier
Adobe Experience Manager Cloud Service (AEM as a Cloud Service)
Content authoring components using form fields vulnerable to script injection

Technical Details for CVE-2025-47062

Vulnerability Analysis

The vulnerability is a stored Cross-Site Scripting flaw in Adobe Experience Manager form field handling. AEM stores user-supplied input from form fields without sufficient neutralization of HTML and JavaScript control characters. When a subsequent user renders the affected page, the injected script executes with the origin and session privileges of that user.

The issue requires an authenticated attacker with low privileges to submit content. A separate victim interaction is required to trigger the payload. The scope changes when the payload runs, meaning the script can affect resources beyond the vulnerable component, including administrative interfaces sharing the same origin.

Root Cause

The root cause is improper neutralization of input during web page generation [CWE-79]. AEM form field processing accepts markup and script content, persists it to the content repository, and later renders it into HTML without contextual output encoding. Missing escaping of characters such as <, >, ", and ' allows attacker input to break out of the intended data context and enter an executable script context.

Attack Vector

Exploitation requires the attacker to authenticate to AEM with a low-privileged account, such as a content author, and locate a form field that fails to sanitize input. The attacker submits a payload containing JavaScript, which AEM stores in the JCR repository. When any user, including an administrator, loads the page containing the field, the browser parses the injected markup and executes the script in the AEM origin context.

Because the vulnerability requires user interaction and produces a scope change, the payload can perform actions in the victim's authenticated session, including reading session tokens, performing CSRF-like actions against AEM APIs, or defacing content served to other users. See the Adobe Security Advisory APSB25-48 for vendor guidance.

Detection Methods for CVE-2025-47062

Indicators of Compromise

Unexpected <script>, onerror=, onload=, or javascript: strings stored in JCR nodes backing form field content
Content author accounts submitting page updates containing HTML entities or encoded script fragments outside their normal editorial patterns
Outbound requests from authenticated administrator browser sessions to unfamiliar external domains shortly after loading authored pages
Anomalous session token usage originating from browser sessions rather than typical API clients

Detection Strategies

Query the JCR repository for stored properties containing script-related keywords, event handler attributes, or data: and javascript: URI schemes
Review AEM access logs for POST requests from low-privileged authors that write to form field properties with unusually large or encoded payloads
Compare rendered page output against source content to identify unexpected script execution during preview or publish cycles
Correlate content modification events with subsequent authenticated administrator page views to identify potential payload triggers

Monitoring Recommendations

Enable AEM audit logging for all content modifications and forward events to a centralized SIEM for retention and correlation
Monitor browser Content Security Policy (CSP) violation reports from AEM authoring and publishing environments
Alert on new outbound network destinations from workstations running AEM administrative sessions
Track author account activity for privilege changes or access to components outside assigned content branches

How to Mitigate CVE-2025-47062

Immediate Actions Required

Upgrade on-premises Adobe Experience Manager to the fixed release identified in Adobe Security Advisory APSB25-48
Verify AEM Cloud Service tenants are on the current release stream, which incorporates the vendor fix
Audit existing content for stored scripts by scanning JCR nodes for HTML and JavaScript markup in form field properties
Review and reduce author-level account assignments to enforce least privilege on content contribution roles

Patch Information

Adobe released fixes for CVE-2025-47062 as part of the June 2025 security update cycle. Refer to Adobe Security Advisory APSB25-48 for the exact patched versions, service pack identifiers, and update procedures for both on-premises AEM 6.5.x and AEM as a Cloud Service.

Workarounds

Apply a strict Content Security Policy on AEM authoring and publish instances to restrict inline script execution
Configure the AEM Dispatcher to filter requests writing suspicious payloads to form field endpoints
Restrict form field editing to trusted author groups until the patch is applied
Enable AEM's XSS protection APIs (XSSAPI) in custom components that render user-supplied form content

bash

# Example: query JCR for stored script content indicating potential injection
