CVE-2025-61796
📋 TL;DR
Adobe Experience Manager versions 11.6 and earlier contain a stored XSS vulnerability that allows low-privileged attackers to inject malicious JavaScript into form fields. When victims visit pages containing the compromised fields, their browsers execute the attacker's code. This affects all users of vulnerable AEM installations.
💻 Affected Systems
- Adobe Experience Manager

Attackers could steal session cookies, redirect users to malicious sites, perform actions on behalf of authenticated users, or install malware through drive-by downloads.
Likely Case
Session hijacking, credential theft, or defacement of web pages through injected content.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Requires low-privileged attacker access and victim interaction. Stored XSS persists until cleaned.
