CVE-2024-32881Public exploitNetwork attack vector

Slack bot compromise via unauthenticated token endpoints

Published Apr 26, 2024 · Updated Aug 2, 2024

Improper authorization in Onyx before 0.3.63 allows remote attackers to read and replace Slack bot tokens over the network. The GET and PUT handlers for /api/manage/admin/slack-bot/tokens call fetch_tokens and save_tokens without the current_admin_user dependency that enforces administrator access. Network reachability alone permits token disclosure or replacement, enabling control of the connected Slack bot and access to internal Slack data.
