CVE-2025-47026
📋 TL;DR
A stored Cross-Site Scripting (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. This affects Adobe Experience Manager versions 6.5.22 and earlier.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware on victim systems.
Likely Case
Session hijacking, credential theft, or defacement of web pages through injected content.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access to vulnerable form fields.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.23 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html
Restart Required: Yes
Instructions:
1. Download Adobe Experience Manager 6.5.23 or later from Adobe's official distribution. 2. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Apply the update to all affected instances. 4. Restart the AEM service.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement strict input validation and output encoding for all user-controllable form fields.
Content Security Policy (CSP)
allDeploy a restrictive CSP header to mitigate XSS impact by limiting script execution sources.
🧯 If You Can't Patch
- Restrict low-privileged user access to form editing capabilities.
- Implement web application firewall (WAF) rules to block XSS payloads.
🔍 How to Verify
Check if Vulnerable:
Check Adobe Experience Manager version via AEM Web Console (/system/console) or by examining the CRX package manager.Check Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo 2>/dev/null | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify version is 6.5.23 or later and test form fields for XSS by attempting to inject basic script payloads.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form submission endpoints with script-like payloads in parameters.
- JavaScript or HTML tags in form field submissions in access logs.
Network Indicators:
- HTTP requests containing <script>, javascript:, or other XSS payload patterns in POST data.
