Summary

Coder from 2.26.0 before 2.34.8 contains an incorrect authorization flaw in the GET /api/v2/workspaces/{id}/acl endpoint. The endpoint checks only workspace read access and then fetches group members with an elevated system context, which exposes sensitive information (CWE-200). Authenticated users granted workspace use access can query the endpoint to collect group members' emails, login types, status, and last-seen and creation timestamps.
