CVE-2025-46902
📋 TL;DR
This stored XSS vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into vulnerable form fields. When victims browse pages containing these fields, their browsers execute the attacker's scripts. Organizations using AEM versions 6.5.22 and earlier are affected.
💻 Affected Systems

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, perform session hijacking, deface websites, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Attackers with low privileges could steal session cookies, perform actions on behalf of authenticated users, or conduct phishing attacks against other users.
If Mitigated
With proper input validation and output encoding, the impact is limited to unsuccessful injection attempts that get sanitized.
🎯 Exploit Status
Exploitation requires low-privileged access to vulnerable form fields. No public exploit code is currently available.
🛠️ 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 input validation logic
Content Security Policy
allDeploy strict CSP headers to limit script execution
Add 'Content-Security-Policy' header with script-src directives
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads
- Restrict low-privileged user access to content editing capabilities
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console. If version is 6.5.22 or earlier, system is vulnerable.Check Version:
curl -u admin:password http://localhost:4502/system/console/status-productinfoVerify Fix Applied:
After patching, verify version is 6.5.23 or later. Test form fields with XSS payloads to ensure sanitization.📡 Detection & Monitoring
