CVE-2025-47033: Adobe Experience Manager XSS Vulnerability

CVE-2025-47033 Overview

CVE-2025-47033 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier, as well as AEM Cloud Service. A low-privileged authenticated attacker can inject malicious JavaScript into vulnerable form fields. The payload executes in a victim's browser when the victim views the page containing the affected field. Adobe published the fix in security bulletin APSB25-48. The vulnerability is tracked under CWE-79 (Improper Neutralization of Input During Web Page Generation).

Critical Impact
Authenticated attackers can execute arbitrary JavaScript in victim browsers, enabling session theft, credential harvesting, and unauthorized actions in the AEM administrative context.

Affected Products

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

Technical Details for CVE-2025-47033

Vulnerability Analysis

The flaw resides in Adobe Experience Manager's handling of form field input. AEM fails to properly neutralize script content submitted through vulnerable form fields before persisting and rendering it. When another user, typically an authenticated content author or administrator, navigates to the page containing the tainted field, the browser parses and executes the attacker-controlled JavaScript.

Because the payload is stored server-side, exploitation does not require the victim to click a crafted link. The malicious script runs in the security context of the AEM application origin. This allows the attacker to read authenticated session data, submit requests on the victim's behalf, or pivot to further attacks against the AEM authoring environment.

Exploitation requires attacker authentication with low privileges and user interaction from a victim who loads the affected page. The scope is changed, meaning the attacker's impact extends beyond the initially vulnerable component into other browser-trusted contexts.

Root Cause

The root cause is insufficient output encoding and input sanitization in specific form field rendering paths. AEM stores the raw input containing HTML or JavaScript control characters, then reflects that content into the DOM without escaping angle brackets, quotes, or event handler attributes. This aligns with the CWE-79 weakness class.

Attack Vector

The attack requires network access to the AEM authoring interface and a low-privilege account with permission to edit form content. The attacker submits a payload containing script tags or event handlers through a vulnerable form field. The payload persists in the AEM repository. When a victim loads the containing page, the browser executes the script under the AEM origin.

No verified public exploit is available for CVE-2025-47033 at this time. See the Adobe Security Advisory APSB25-48 for vendor-provided technical details.

Detection Methods for CVE-2025-47033

Indicators of Compromise

Form field content containing <script> tags, javascript: URIs, or DOM event handler attributes such as onerror, onload, or onclick
Unexpected outbound HTTP requests from author browsers to attacker-controlled domains shortly after loading AEM authoring pages
Anomalous session token access or account activity from AEM administrator accounts following page views

Detection Strategies

Review AEM audit logs for form field modifications by low-privileged accounts, especially entries containing HTML markup or encoded script characters
Deploy Content Security Policy (CSP) reporting to surface inline script execution violations on AEM-rendered pages
Scan the AEM JCR repository for stored properties containing suspicious script patterns using tools such as oak-run

Monitoring Recommendations

Monitor authenticated author sessions for privilege changes, new user creation, or workflow modifications that follow page-view events
Alert on outbound network connections from browsers accessing /editor.html or /content/dam paths to unrecognized external hosts
Track failed and successful logins to AEM author instances and correlate with content edits from newly created or infrequently used accounts

How to Mitigate CVE-2025-47033

Immediate Actions Required

Apply the fixes documented in Adobe Security Advisory APSB25-48 to on-premises AEM installations
Confirm AEM Cloud Service instances are running the patched release channel provided by Adobe
Audit user accounts with form-editing permissions and remove unnecessary low-privilege access to authoring components
Review recently modified form fields for injected script content and revert affected pages

Patch Information

Adobe released fixed builds addressing CVE-2025-47033 for AEM 6.5 (versions after 6.5.22) and AEM Cloud Service. Consult Adobe Security Advisory APSB25-48 for exact build numbers, download locations, and installation guidance. Apply the update in a staging environment before production rollout.

Workarounds

Enforce a strict Content Security Policy on AEM author and publish instances to block inline script execution
Restrict form-editing permissions to trusted authors and enable multi-factor authentication for all AEM accounts
Place AEM author instances behind a Web Application Firewall (WAF) configured with rules to filter script payloads in form submissions
Disable or remove unused form components that accept rich text input from low-privilege users

bash

# Example CSP header for AEM dispatcher configuration
Header set Content-Security-Policy "default-src 'self'; script-src 'self' 'nonce-{random}'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'"
