CVE-2025-46974
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored XSS vulnerability where low-privileged attackers can inject malicious scripts into form fields. When users visit pages with these compromised fields, their browsers execute the attacker's JavaScript. This affects organizations using vulnerable AEM instances for content management.
💻 Affected Systems
- Adobe Experience Manager
📦 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 deploy ransomware-like attacks within the browser context.
Likely Case
Session hijacking, credential theft, or defacement of web content through injected scripts.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy headers in place.
🎯 Exploit Status
Exploitation requires authenticated low-privilege 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

🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Add 'Content-Security-Policy: default-src 'self'; script-src 'self'' to web server configuration
Input Validation Filter
allDeploy servlet filter to sanitize form inputs
Configure AEM filter to strip/encode HTML/JS from user inputs
🧯 If You Can't Patch
- Restrict low-privileged user access to content editing interfaces
- Implement web application firewall rules to block XSS payload patterns
