Description

Adobe Connect versions 2025.3, 12.10 and earlier are affected by a Cross-Site Scripting (XSS) vulnerability that could result in privilege escalation. A low-privileged attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially gaining elevated access or control over the victim's account or session. Exploitation of this issue requires user interaction in that a victim must visit a maliciously crafted URL or interact with a compromised web page. Scope is changed.
