This vulnerability allows a low-privileged attacker to inject malicious scripts into a web page viewed by other users. Successful exploitation requires user interaction, such as clicking a crafted URL or interacting with a compromised page within the Adobe Connect environment. The vulnerability could allow an attacker to gain elevated access or control over a victim\u0026rsquo;s account or session.
