CVE-2025-46963
📋 TL;DR
A 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 fields, their browsers execute the attacker's scripts. This affects Adobe Experience Manager versions 6.5.22 and earlier.

Likely Case
Session hijacking, credential theft, defacement of web pages, or data exfiltration from user browsers.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access to vulnerable form fields.
🛠️ Fix & Mitigation
