Technical description

wire-server provides back end services for Wire, a team communication and collaboration platform. Prior to version 2022-12-09, every member of a Conversation can remove a Bot from a Conversation due to a missing permissions check. Only Conversation admins should be able to remove Bots. Regular Conversations are not allowed to do so. The issue is fixed in wire-server 2022-12-09 and is already deployed on all Wire managed services. On-premise instances of wire-server need to be updated to 2022-12-09/Chart 4.29.0, so that their backends are no longer affected. There are no known workarounds.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
