CVE-2025-46967
📋 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 containing 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 additional malware payloads through the compromised browser sessions.
Likely Case
Session hijacking, credential theft, defacement of web content, or limited data exfiltration from user browsers accessing the vulnerable pages.
If Mitigated
With proper input validation and output encoding controls, the vulnerability would be prevented, resulting in no impact.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access to vulnerable form fields. The vulnerability is well-understood (CWE-79) with common exploitation patterns.
🛠️ 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
Input Validation and Output Encoding
allImplement server-side input validation and proper output encoding for all user-controllable form fields
Content Security Policy
allDeploy a strict Content Security Policy header to mitigate XSS impact
Content-Security-Policy: default-src 'self'; script-src 'self'
🧯 If You Can't Patch
- Restrict low-privileged user access to form editing capabilities
- Implement web application firewall rules to block XSS payload patterns
🔍 How to Verify
Check if Vulnerable:
Check AEM version via the welcome screen or system console. Versions 6.5.22 or earlier are vulnerable.Check Version:
Navigate to AEM welcome screen or use curl: curl -k https://aem-host:port/system/console/status-productinfoVerify Fix Applied:
Verify AEM version is 6.5.23 or later. Test form fields with safe XSS payloads to confirm proper sanitization.📡 Detection & Monitoring
