CVE-2025-47063: Adobe Experience Manager XSS Vulnerability

CVE-2025-47063 Overview

Adobe Experience Manager (AEM) versions 6.5.22 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability [CWE-79]. A low-privileged attacker can inject malicious JavaScript into vulnerable form fields. The payload executes in a victim's browser when they load the page containing the compromised field.

The flaw affects both on-premise Adobe Experience Manager installations and the AEM Cloud Service. Exploitation requires attacker authentication and victim interaction, but crosses a security scope boundary once triggered.

Critical Impact
Stored JavaScript payloads execute in the context of authenticated AEM users, enabling session theft, content defacement, and unauthorized actions performed on behalf of victims.

Affected Products

Adobe Experience Manager 6.5.22 and earlier (on-premise)
Adobe Experience Manager Cloud Service (AEM as a Cloud Service)
AEM instances exposing form authoring or content input fields

Technical Details for CVE-2025-47063

Vulnerability Analysis

The vulnerability is a stored Cross-Site Scripting flaw in Adobe Experience Manager form handling logic. AEM fails to properly sanitize or encode user-supplied input written to specific form fields. The malicious content persists in AEM's content repository and is served back to any user who renders the affected page.

Because the injected script executes in the victim's browser under the origin of the AEM instance, attackers can steal session tokens, perform CSRF-style actions, or pivot into administrative workflows. The scope change component of the risk profile indicates the payload can affect resources beyond the vulnerable component itself.

Root Cause

The root cause is insufficient output encoding or input validation on form fields exposed to authenticated authors and contributors. AEM stores the raw payload in the Java Content Repository (JCR) and renders it without escaping HTML or JavaScript context markers.

CWE-79 (Improper Neutralization of Input During Web Page Generation) governs this class of flaw. The design assumption that low-privileged content contributors would submit trusted input does not hold in multi-tenant or externally exposed AEM environments.

Attack Vector

An authenticated attacker with content-authoring privileges submits a form field value containing a JavaScript payload. AEM persists the payload in the repository. When a victim (typically an author, reviewer, or administrator) navigates to the affected page, the browser parses the payload as executable script.

Exploitation requires user interaction, so social engineering or routine content review workflows serve as the trigger. See the Adobe Security Advisory APSB25-48 for vendor-specific technical detail.

Detection Methods for CVE-2025-47063

Indicators of Compromise

Form field content in JCR containing <script>, javascript:, onerror=, onload=, or encoded variants such as <script>
Unexpected outbound HTTP requests from AEM author or publish instances originating from browser sessions
Repository nodes with unusual property values under /content/ or /etc/ form components

Detection Strategies

Scan JCR content for stored HTML or JavaScript syntax in text and rich-text form properties
Review AEM access logs for POST requests to form endpoints containing script-like payloads
Correlate authoring activity from low-privileged accounts with subsequent anomalous session behavior on author instances

Monitoring Recommendations

Enable AEM audit logging for content modifications and export events to a centralized SIEM
Alert on Content Security Policy (CSP) violations reported by browsers rendering AEM pages
Monitor for privilege escalation or session hijack patterns following content publication events

How to Mitigate CVE-2025-47063

Immediate Actions Required

Upgrade Adobe Experience Manager to the version specified in Adobe Security Advisory APSB25-48
Audit form authoring permissions and remove unnecessary content contributor accounts
Review recently modified form components in the JCR for injected script content

Patch Information

Adobe released fixed builds addressing this issue as documented in Adobe Security Advisory APSB25-48. AEM as a Cloud Service customers receive the fix through Adobe's managed update pipeline. On-premise operators must apply the AEM 6.5 Service Pack referenced in the advisory.

Workarounds

Deploy a strict Content Security Policy (CSP) that blocks inline script execution on AEM-rendered pages
Restrict form authoring privileges to trusted users and enforce content review before publication
Place a web application firewall (WAF) in front of AEM to filter script-like payloads in form submissions
Sanitize existing form field content in the JCR using AEM's XSSAPI utilities before rendering

bash

# Example: query JCR for stored script content using AEM's built-in JCR SQL2
# Run from the AEM CRXDE Lite query tool
SELECT * FROM [nt:unstructured] AS node
WHERE ISDESCENDANTNODE(node, '/content')
AND (CONTAINS(node.*, 'script')
     OR CONTAINS(node.*, 'onerror')
     OR CONTAINS(node.*, 'javascript:'))
