CVE-2025-64872
📋 TL;DR
This stored XSS vulnerability in Adobe Experience Manager allows high-privileged attackers to inject malicious JavaScript into form fields. When victims browse pages containing the compromised fields, their browsers execute the attacker's code. Only Adobe Experience Manager versions 6.5.23 and earlier are affected.
💻 Affected Systems

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
High-privileged attacker steals admin credentials, performs session hijacking, or deploys ransomware through malicious scripts.
Likely Case
Privileged user account compromise leading to data theft, defacement, or lateral movement within the AEM environment.
If Mitigated
Limited impact due to proper input validation, output encoding, and least privilege access controls.
🎯 Exploit Status
Exploitation requires high-privileged credentials; stored XSS is straightforward once authenticated.
