CVE-2025-49552 is a DOM-based cross-site scripting vulnerability affecting Adobe Connect versions 12.9 and earlier on Windows and macOS. The flaw allows a high-privileged attacker to cause malicious script execution within a victim's browser by leveraging unsafe client-side handling of attacker-controlled input in the web application. Exploitation requires user interaction, specifically that the victim navigate to a crafted web page. Because the script executes in the security context of the Adobe Connect application, the vulnerability can compromise browser-session trust boundaries and has changed scope.
