CVE-2025-47032: Adobe Experience Manager XSS Vulnerability

CVE-2025-47032 Overview

CVE-2025-47032 is a stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager (AEM) versions 6.5.22 and earlier, as well as AEM Cloud Service. A low-privileged attacker can inject malicious JavaScript into vulnerable form fields. The payload executes in a victim's browser when they load the affected page. The weakness is classified under CWE-79, Improper Neutralization of Input During Web Page Generation. Adobe published guidance in Adobe Security Advisory APSB25-48.

Critical Impact
Authenticated attackers can persist JavaScript in AEM form fields, enabling session theft, credential harvesting, and unauthorized actions within a victim's authenticated context.

Affected Products

Adobe Experience Manager 6.5.22 and earlier (on-premises)
Adobe Experience Manager Cloud Service (AEM CS)
AEM Forms components rendering unsanitized user input

Technical Details for CVE-2025-47032

Vulnerability Analysis

The flaw resides in Adobe Experience Manager form field handling. AEM stores attacker-supplied input without sufficient output encoding or input sanitization. When a subsequent user renders the affected page, the browser interprets injected markup as executable script. Because the payload is stored server-side, exploitation persists across sessions and affects every visitor to the impacted page.

The scope-changing nature of the flaw means injected script executes in the context of the AEM application's origin. Attackers can leverage this to read authenticated content, issue requests on behalf of the victim, or pivot toward administrative functionality if a privileged user views the compromised page.

Root Cause

The root cause is improper neutralization of user input written into HTML output ([CWE-79]). AEM accepts data submitted through form fields and later reflects that content into rendered pages without escaping HTML-significant characters. This allows an attacker with authoring or form-submission privileges to embed <script> tags or event-handler attributes that survive persistence and are served back to end users.

Attack Vector

Exploitation requires network access to the AEM instance, low-level authenticated privileges, and user interaction. A typical attack chain proceeds as follows:

An attacker authenticates to AEM with a low-privileged account.
The attacker submits a JavaScript payload into a vulnerable form field, such as an authoring or component input.
AEM persists the malicious content without encoding.
A victim navigates to the page containing the field.
The payload executes in the victim's browser under the AEM origin, enabling cookie theft, DOM manipulation, or forced actions.

Because no public proof-of-concept or in-the-wild exploitation has been reported, the immediate risk aligns with the CWE-79 stored XSS pattern rather than a known exploit chain.

Detection Methods for CVE-2025-47032

Indicators of Compromise

Form field content containing <script>, javascript: URIs, or HTML event handlers such as onerror= and onload=.
Unexpected outbound requests from user browsers to attacker-controlled domains shortly after loading AEM pages.
Unusual Referer headers in AEM access logs pointing to internal authoring endpoints from external destinations.
Session cookies appearing in third-party request logs sourced from AEM-rendered pages.

Detection Strategies

Review AEM content repositories and form submissions for HTML or JavaScript payloads stored in text fields.
Enable a Content Security Policy (CSP) in report-only mode to surface inline script executions that violate policy.
Correlate authoring activity logs with subsequent client-side errors or CSP violation reports.
Inspect web application firewall (WAF) telemetry for POST requests containing script tags or encoded XSS payloads targeting AEM endpoints.

Monitoring Recommendations

Forward AEM access, dispatcher, and authoring logs to a centralized analytics platform for query and alerting.
Alert on repeated failed submissions containing script-like tokens from the same low-privileged account.
Monitor for unexpected privilege escalations or session anomalies following views of author-generated content.

How to Mitigate CVE-2025-47032

Immediate Actions Required

Upgrade Adobe Experience Manager to the fixed version listed in Adobe Security Advisory APSB25-48.
Audit low-privileged AEM accounts and revoke unnecessary authoring or form-submission permissions.
Scan existing form field content for persisted script payloads and remove any malicious entries.
Rotate session tokens and administrative credentials if compromise is suspected.

Patch Information

Adobe addressed the vulnerability in the release documented in APSB25-48. Customers running AEM 6.5.22 or earlier must apply the vendor-supplied service pack. AEM Cloud Service customers receive the fix through Adobe's managed release channel and should confirm their tenant is on the updated build.

Workarounds

Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins.
Deploy WAF rules that filter HTML tags and JavaScript event handlers from form submissions to AEM endpoints.
Restrict authoring and form-submission privileges to vetted users until the patch is applied.
Enable output encoding in custom AEM components that render user-supplied field data.
