CVE-2023-36535Network attack vector

Authenticated information disclosure

Published Aug 8, 2023 · Updated Oct 8, 2024

Client-side security enforcement in Zoom Clients before 5.14.10 allows remote authenticated users to disclose information via network access. Zoom identifies the locus only as client-side enforcement of server-side security and has not published the specific control or operation that exposes data. Exploitation requires an authenticated network user, and the public record does not identify the information exposed or the affected client feature.
