CVE-2024-33850Network attack vector

Conference data exposure via incomplete waiting-room checks

Published Jun 10, 2024 · Updated Nov 21, 2024

Improper access control in Pexip Infinity 4 through 34.0 allows remote authenticated users in a waiting room to access conference data. Incomplete checks let waiting-room participants retrieve the roster and invoke conference actions using the role they would receive after admission. The user must first authenticate under the conference access policy, and available actions are limited by the pending host or guest role.
