How CVE-2025-46886 Works
This stored XSS vulnerability in Adobe Experience Manager (AEM) 6.5.22 and earlier allows attackers with low privileges to inject malicious JavaScript into vulnerable form fields. The payload persists in the backend and executes when victims access the compromised page. Attackers exploit insufficient input sanitization in web form submissions, bypassing client-side filters to store harmful scripts in the database. When rendered, these scripts execute in the victim’s browser, enabling session hijacking, phishing, or malware delivery. The attack requires no user interaction beyond viewing the infected page, amplifying its impact.
DailyCVE Form
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/12/2025
Prediction: Patch expected by 07/15/2025
What Undercode Say:
Exploitation
1. Payload Crafting:
<script>alert(document.cookie)</script>
2. Injection via Form:
curl -X POST -d "field=<malicious_script>" http://victim-aem/formsubmit
3. Persistence Check:
SELECT FROM aem_forms WHERE field LIKE '%script%';
Protection
1. Input Sanitization:
String sanitized = ESAPI.encoder().encodeForHTML(userInput);
2. Content Security Policy (CSP):
Header set Content-Security-Policy "default-src 'self'; script-src 'unsafe-inline'"
3. Patch Verification:
aemcli --version | grep "6.5.23"
Analytics
- Attack Surface: Web forms, comment modules.
- Mitigation Difficulty: Medium (requires backend validation upgrades).
- Exploit Prevalence: High (due to low privilege requirement).
Detection Commands
