CVE-2021-32646Network attack vector

Channel takeover via caller permission overwrite

Published May 28, 2021 · Updated Aug 3, 2024

Improper authentication in the Roomer cog of Dav-Cogs before 1.0.1 allows remote authenticated users to control joined private voice channels. The hidden command builds a permission-overwrite map that grants manage_channels to the invoking member rather than preserving existing channel permissions. The user must already have joined a generated private voice channel; control is limited to changing or deleting that channel.
