CVE-2022-28763 is a critical URL parsing vulnerability affecting Zoom Client for Meetings across multiple operating systems, Zoom Rooms, and Zoom VDI. With a CVSS score of 9.6, this vulnerability allows an attacker to redirect users to arbitrary network addresses via a malicious Zoom meeting URL, potentially leading to session takeovers and other severe impacts.
