CVE-2025-46985
📋 TL;DR
A stored Cross-Site Scripting vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into vulnerable form fields. When users visit pages containing the compromised fields, their browsers execute the attacker's code. This affects AEM versions 6.5.22 and earlier.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, perform actions as authenticated users, deface websites, or redirect users to malicious sites.
Likely Case
Session hijacking, credential theft, or unauthorized content modification by authenticated low-privileged users.
If Mitigated
Limited to same-origin attacks with minimal impact if proper input validation and output encoding are implemented.
🎯 Exploit Status
Exploitation requires authenticated access but is technically simple once access is obtained.
