How CVE-2025-46859 Works
Adobe Experience Manager (AEM) 6.5.22 and earlier fails to properly sanitize user-supplied input in form fields, allowing attackers with low privileges to inject malicious JavaScript payloads. When an administrator or high-privileged user accesses the compromised page, the script executes in their browser session, potentially leading to session hijacking, data theft, or unauthorized actions within AEM. The vulnerability stems from insufficient input validation in the WCM (Web Content Management) component, where crafted HTML/JavaScript persists in the database and renders without escaping.
DailyCVE Form

Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/12/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Exploitation Analysis
1. Payload Injection:
<script>alert(document.cookie)</script>
Submitted via vulnerable form fields (e.g., text inputs, rich text editors).
2. Persistence:
Malicious scripts are stored in AEM’s JCR repository and served to victims.
3. Impact:
Steal session cookies, redirect to phishing pages, or escalate privileges via CSRF.
Protection Commands
1. Input Sanitization:
// OWASP Java HTML Sanitizer PolicyFactory policy = new HtmlPolicyBuilder().toFactory(); String safeInput = policy.sanitize(userInput);
2. AEM Filter Mitigation:
<!-- /apps/cq/config/rewriter/default.xml --> <rules jcr:primaryType="nt:unstructured"> <xss type="string">on</xss> </rules>
3. Patch Verification:
curl -I http://aem-instance/system/console/status-productinfo | grep "AEM 6.5.23"
Detection Script
import requests
target = "http://aem-instance/content/forms/feedback.html"
payload = "<img src=x onerror=alert(1)>"
response = requests.post(target, data={"comment": payload})
if payload in response.text:
print("Vulnerable to CVE-2025-46859")
Post-Patch Actions
1. Audit Logs:
SELECT FROM crx_repository WHERE path LIKE '%/forms/%' AND data LIKE '%<script>%';
2. WAF Rule:
location /content/forms/ {
modsecurity_rules 'SecRule ARGS "@rx <script>" "id:1001,deny,status:403"';
}
3. Disable Risky Components:
curl -u admin:password -X POST -F "enabled=false" http://aem-instance/system/console/components/com.adobe.cq.wcm.core.components.forms.FormContainer
