CVE-2025-46981: Adobe Experience Manager XSS Vulnerability

CVE-2025-46981 Overview

Adobe Experience Manager (AEM) versions 6.5.22 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability [CWE-79]. A low-privileged authenticated attacker can inject malicious JavaScript into vulnerable form fields. The payload executes in the browser of any victim who visits the page rendering the affected field.

The flaw affects both the on-premises AEM 6.5.x line and the AEM Cloud Service. Exploitation requires user interaction because the victim must load the page hosting the injected content. Adobe published the fix in Security Bulletin APSB25-48.

Critical Impact
Attackers can execute arbitrary JavaScript in victim browsers, enabling session token theft, forced actions on behalf of the user, and phishing content injection within the trusted AEM domain.

Affected Products

Adobe Experience Manager 6.5.22 and earlier (on-premises)
Adobe Experience Manager Cloud Service (affected releases)
Author instances exposing form authoring components

Technical Details for CVE-2025-46981

Vulnerability Analysis

The vulnerability is a stored XSS flaw in AEM form field handling. An authenticated user with content-authoring permissions can supply JavaScript payloads through form field inputs. AEM persists the input without sufficient output encoding or sanitization.

When another user renders the page containing the affected field, the stored payload executes in the victim's browser session. Because the script runs in the AEM origin, it inherits access to session cookies, DOM content, and any authenticated API endpoints the victim can reach.

The scope change reflected in the CVSS vector indicates the injected script can affect resources beyond the vulnerable component. This aligns with typical browser same-origin behavior where XSS in one AEM page can pivot to administrative interfaces served from the same host.

Root Cause

The root cause is missing or insufficient neutralization of user-controlled input during web page generation, as classified by CWE-79. Form field values are stored and later rendered without contextual output encoding appropriate for HTML, attribute, or JavaScript contexts.

Attack Vector

An attacker requires low-privileged authenticated access to an AEM author instance capable of editing form fields. The attacker injects a JavaScript payload into a vulnerable field and saves the content. When a victim, including higher-privileged administrators, browses to the page rendering that field, the script executes.

See the Adobe Security Advisory APSB25-48 for the vendor description of the affected components. No public proof-of-concept exploit code is available at time of writing.

Detection Methods for CVE-2025-46981

Indicators of Compromise

Unexpected <script> tags, event handler attributes (onerror=, onload=), or javascript: URIs stored in AEM form field content nodes under /content in the JCR repository.
Outbound requests from author or publish instances to unfamiliar domains that could indicate exfiltration of session tokens.
Unusual authenticated actions performed shortly after an administrator loaded a content-authoring page.

Detection Strategies

Audit JCR content nodes for stored HTML or JavaScript payloads in form component properties using AEM query builder or curl against the QueryBuilder API.
Review AEM access.log and request.log entries for POST requests to form-editing endpoints followed by GET requests loading the same page from other user sessions.
Enable and monitor Content Security Policy (CSP) violation reports to catch inline script execution originating from persisted content.

Monitoring Recommendations

Alert on modifications to form component properties by non-administrative accounts.
Correlate authoring activity with administrator page views to identify potential victim exposure windows.
Track anomalous cookie or token usage patterns from AEM sessions consistent with post-XSS session hijacking.

How to Mitigate CVE-2025-46981

Immediate Actions Required

Upgrade on-premises AEM to the fixed version published in Adobe Security Bulletin APSB25-48.
Verify AEM Cloud Service instances have received the corresponding service update.
Review content authoring accounts and revoke unnecessary form-editing permissions.
Rotate session secrets and force re-authentication if suspicious form field content is found.

Patch Information

Adobe addressed CVE-2025-46981 in the security update documented in Adobe Security Advisory APSB25-48. Apply the AEM 6.5 Service Pack referenced in the bulletin, or confirm the AEM Cloud Service release includes the fix. Adobe rates the update priority in the bulletin; follow the vendor guidance for scheduling.

Workarounds

Restrict form authoring privileges to a minimal set of trusted users until patching is complete.
Deploy a strict Content Security Policy that blocks inline scripts and unknown external script sources on author and publish tiers.
Place a web application firewall in front of AEM to inspect and block payloads containing HTML or JavaScript in form field submissions.
Enable AEM's Sling referrer filter and CSRF protections to reduce the blast radius of successful script execution.

bash
