Description
Coder from 2.26.0 before 2.34.8 contains an incorrect authorization flaw in the GET /api/v2/workspaces/{id}/acl endpoint, which checks only workspace read access and then fetches group members using an elevated system context. Authenticated users granted workspace use access can query the endpoint to harvest group members' emails, login types, status, and last-seen and creation timestamps.
