Adobe Experience Manager Screens versions FP11.3 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field. Exploitation of this issue requires user interaction in that a victim must open a malicious link.
