CVE-2025-46929
📋 TL;DR
This stored XSS vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into form fields. When victims visit pages containing the compromised fields, their browsers execute the attacker's code. Organizations using AEM versions 6.5.22 or earlier are affected.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface websites, or redirect users to malicious sites, potentially leading to complete system compromise.
Likely Case
Attackers with low privileges could steal session cookies, perform actions as authenticated users, or conduct phishing attacks against other users.
If Mitigated
With proper input validation and output encoding, the risk is limited to specific vulnerable form fields that might still exist despite security controls.
🎯 Exploit Status
Exploitation requires low-privileged access to vulnerable form fields; stored XSS payloads persist until cleaned.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.23 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html

🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize user input in form fields
Implement Java servlet filter with OWASP Java Encoder library for input sanitization
Content Security Policy
allDeploy strict CSP headers to limit script execution
Add 'Content-Security-Policy: script-src 'self'' to AEM dispatcher configuration
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads
- Disable or restrict low-privileged user access to vulnerable form fields
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console; versions 6.5.22 or earlier are vulnerableCheck Version:
curl -u admin:password http://localhost:4502/system/console/status-productinfoVerify Fix Applied:
Verify AEM version is 6.5.23 or later and test form fields with XSS payloads📡 Detection & Monitoring
