CVE-2023-22737Network attack vector

Unauthorized bot removal via missing conversation-role check

Published Jan 27, 2023 · Updated Mar 10, 2025

Missing authorization in Wire Swiss GmbH Wire Server before 2022-12-09 allows remote authenticated users to remove bots from conversations. The Brig removeBot handler fetched the conversation and deleted the bot without first requiring the caller's self-member role to equal Wire administrator. Any conversation member could invoke the operation, interrupting the bot's participation in that conversation without changing other server data.
