CVE-2025-47000: Adobe Experience Manager XSS Vulnerability

CVE-2025-47000 Overview

CVE-2025-47000 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier, including the AEM Cloud Service. A low-privileged attacker can inject malicious JavaScript into vulnerable form fields. The payload persists in the application and executes in a victim's browser when they visit the page containing the affected field. Exploitation requires user interaction and results in a scope change, allowing attackers to affect resources beyond the vulnerable component. The vulnerability is categorized under CWE-79, Improper Neutralization of Input During Web Page Generation.

Critical Impact
Authenticated attackers can inject persistent JavaScript into AEM form fields, enabling session hijacking, credential theft, and content manipulation against any user who views the affected page.

Affected Products

Adobe Experience Manager 6.5.22 and earlier on-premise versions
Adobe Experience Manager Cloud Service (AEM as a Cloud Service)
Adobe Experience Manager Forms components with vulnerable input fields

Technical Details for CVE-2025-47000

Vulnerability Analysis

The flaw is a stored (persistent) XSS in Adobe Experience Manager form field handling. AEM fails to properly neutralize user-supplied input before storing it and rendering it back within HTML output. When a victim visits a page that embeds the tainted field, the browser executes the attacker-controlled JavaScript within the origin of the AEM application.

Exploitation requires an attacker with low-level authenticated access, typically an author or contributor role capable of editing form components. The attack requires user interaction, since a victim must load the page containing the injected payload. Successful exploitation causes a scope change, meaning the executed script can influence resources beyond the AEM component that stored it, including the victim's authenticated session.

Attackers can leverage the executed script to steal session cookies, perform actions on behalf of higher-privileged administrators, deface content, or pivot to internal AEM administrative interfaces reachable from the victim's browser.

Root Cause

The root cause is improper output encoding and input sanitization within specific AEM form field components. Content submitted through the affected fields is stored in the repository and later rendered into HTML pages without adequate HTML entity encoding or context-aware escaping. See CWE-79 for background on this vulnerability class.

Attack Vector

The attack is delivered over the network against the AEM author or publish instance. A low-privileged authenticated attacker submits a JavaScript payload, such as an <img> tag with an onerror handler or a <script> block, into a vulnerable form field. The payload is persisted server-side. When a higher-privileged user or site visitor renders the page, their browser parses and executes the stored script under the AEM domain's origin.

Because the vulnerability requires only low privileges and network access, it is well suited to insider abuse or exploitation via compromised contributor accounts. No verified public proof-of-concept code is available at this time. Refer to the Adobe Security Advisory APSB25-48 for vendor-provided technical detail.

Detection Methods for CVE-2025-47000

Indicators of Compromise

Stored content in AEM repositories containing HTML tags such as <script>, <svg onload=>, <img onerror=>, or javascript: URIs inside form field values.
Unexpected outbound requests from authenticated user browsers to attacker-controlled domains referencing AEM session tokens or cookies.
Content Security Policy (CSP) violation reports originating from AEM-hosted pages containing inline script executions.
Modifications to form components by low-privileged accounts followed by anomalous access patterns from higher-privileged users.

Detection Strategies

Scan the AEM JCR repository for stored field values containing HTML or JavaScript syntax that should not appear in text-only fields.
Deploy web application firewall (WAF) rules that inspect POST bodies to AEM form endpoints for common XSS payload signatures.
Correlate author-tier content edits with subsequent client-side errors, CSP violations, or unusual navigation events logged from publish instances.
Review AEM audit logs for content edits made by low-privileged accounts targeting form components in high-visibility pages.

Monitoring Recommendations

Enable and centralize AEM AuditLog and RequestLog collection into a SIEM for correlation with browser-side telemetry.
Instrument published pages with a strict Content Security Policy that reports inline script violations to a dedicated endpoint.
Monitor for privileged administrator sessions loading pages recently modified by low-privileged authors.
Track EPSS score changes for CVE-2025-47000 to reassess exploitation likelihood over time.

How to Mitigate CVE-2025-47000

Immediate Actions Required

Apply the Adobe security updates referenced in APSB25-48 to all AEM on-premise instances running 6.5.22 or earlier.
Verify that AEM as a Cloud Service tenants are receiving the vendor-managed patch and confirm the release version reflects the fix.
Audit low-privileged author accounts for recent edits to form components and review content for injected scripts.
Rotate session tokens and administrative credentials if evidence of exploitation is found.

Patch Information

Adobe addressed CVE-2025-47000 in the security update tracked as APSB25-48. Customers running AEM 6.5.22 or earlier must upgrade to the fixed service pack identified in the Adobe Security Advisory APSB25-48. AEM Cloud Service customers receive the fix through Adobe's managed release channel.

Workarounds

Restrict author-tier permissions so that only trusted users can edit form components until patching is complete.
Deploy a strict Content Security Policy on published sites to block inline script execution and reduce XSS impact.
Configure a WAF in front of AEM author and publish instances to filter common XSS payloads in form submissions.
Enforce HttpOnly and Secure flags on AEM session cookies to limit token theft from injected scripts.
