CVE-2025-46923
📋 TL;DR
This stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into vulnerable form fields. When victims browse pages containing these compromised fields, their browsers execute the attacker's scripts. Organizations using Adobe Experience Manager versions 6.5.22 and earlier are affected.

⚠️ 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, potentially leading to complete system compromise.
Likely Case
Attackers with low privileges steal user session tokens or credentials, perform limited unauthorized actions within the application, or deploy basic phishing attacks.
If Mitigated
With proper input validation and output encoding controls, the vulnerability would be prevented, though the underlying code flaw remains.
🎯 Exploit Status
Exploitation requires low-privileged access to vulnerable form fields. The vulnerability is well-understood (CWE-79) with common exploitation patterns.
