CVE-2025-47083: Adobe Experience Manager XSS Vulnerability

CVE-2025-47083 Overview

CVE-2025-47083 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier, including the AEM Cloud Service. The flaw resides in vulnerable form field handling, where a low-privileged authenticated attacker can inject malicious JavaScript that persists in the application. When a victim browses to the page containing the affected field, the malicious script executes in their browser context. The vulnerability is tracked under CWE-79 (Improper Neutralization of Input During Web Page Generation). Adobe published the fix in security bulletin APSB25-48.

Critical Impact
Authenticated attackers can inject persistent JavaScript into AEM form fields, leading to session compromise, credential theft, and unauthorized actions in the victim's browser context.

Affected Products

Adobe Experience Manager 6.5.22 and earlier (on-premise)
Adobe Experience Manager Cloud Service (affected releases prior to fix)
AEM components rendering user-controlled form field content

Technical Details for CVE-2025-47083

Vulnerability Analysis

The vulnerability is a stored XSS flaw in Adobe Experience Manager form components. AEM fails to properly neutralize script content submitted through affected form fields before persisting and rendering that content back to other users. Because the payload is stored server-side, every user who views the affected page triggers script execution without further attacker interaction beyond the initial injection.

Exploitation requires an attacker to hold a low-privileged authenticated account with permission to submit or edit form field content. Successful exploitation runs script code in the victim's browser under the origin of the AEM site, enabling session hijacking, forced browser actions, and content defacement. The scope change indicates that impact can extend beyond the vulnerable component to other resources the victim can access.

Root Cause

The root cause is improper output encoding and input sanitization on form field values within affected AEM components. User-supplied markup is rendered into the HTML response without contextual escaping, allowing <script> blocks and event handler attributes to survive server-side processing and reach the victim's browser as executable code.

Attack Vector

The attack is delivered over the network against AEM instances that expose vulnerable authoring or form submission interfaces. An attacker authenticates with a low-privilege account, injects a JavaScript payload into a susceptible form field, and waits for a higher-privileged user or site visitor to load the page. User interaction is required to trigger the stored payload. The vulnerability mechanism is described in the Adobe Security Advisory APSB25-48; no public proof-of-concept exploit is available.

Detection Methods for CVE-2025-47083

Indicators of Compromise

Form field values or content nodes in the AEM JCR repository containing <script>, onerror=, onload=, or javascript: payloads.
Unexpected outbound HTTP requests from browsers of authenticated AEM users to attacker-controlled domains.
Anomalous session token access or administrative actions performed shortly after a user views an affected page.

Detection Strategies

Review AEM access and request logs for POST requests to form or component endpoints containing encoded script payloads submitted by low-privileged accounts.
Query the JCR repository for stored properties containing HTML or JavaScript syntax in fields that should hold plain text.
Enable and monitor Content Security Policy (CSP) violation reports for inline script execution originating from AEM-hosted pages.

Monitoring Recommendations

Alert on authoring activity from newly created or low-privilege accounts modifying form components outside expected workflows.
Correlate browser telemetry from privileged users with page loads of recently modified AEM content to detect payload execution.
Track authentication anomalies such as session reuse from unexpected IP addresses following visits to modified pages.

How to Mitigate CVE-2025-47083

Immediate Actions Required

Upgrade Adobe Experience Manager to the fixed release identified in Adobe Security Bulletin APSB25-48; AEM Cloud Service customers receive fixes automatically.
Audit existing form field content and component properties for stored script payloads and remove any that are found.
Rotate session tokens and credentials for any users who may have viewed compromised pages.

Patch Information

Adobe addressed CVE-2025-47083 in the release documented in APSB25-48, published on 2025-06-10. On-premise operators must upgrade beyond AEM 6.5.22 to the patched Service Pack. AEM as a Cloud Service instances are patched by Adobe on the managed release schedule.

Workarounds

Restrict authoring and form submission permissions to trusted accounts until the patch is deployed.
Deploy a strict Content Security Policy that blocks inline scripts and untrusted script sources on AEM-hosted pages.
Place a web application firewall in front of AEM to filter script-like payloads in form field submissions.
