CVE-2024-33530Public exploitNetwork attack vector

Meeting-password disclosure via XMPP lobby invitations

Published May 2, 2024 · Updated Apr 9, 2025

Logic flaw in Jitsi Meet 1.0.4289 through 2.0.9364 allows remote attackers to obtain a meeting password through a lobby invitation. An approved lobby user's XMPP mediated-invite message includes the room password, while Jitsi treats anyone presenting that password as a room member. Access requires a password-protected meeting with lobby mode and an invitation, after which the recipient can share the password to admit others without moderator rights.
