CVE-2026-111930 · Severity: medium · CVSS 4.3 · Published 2026-10-17

Coder is a platform that provides remote development environments accessible through web-based workspaces. An authorization flaw in the workspace ACL endpoint allows authenticated users with basic workspace access to view personally identifiable information of all group members associated with that workspace, including email addresses, login types, and activity timestamps. An attacker could use this data harvesting capability for phishing campaigns or to map organizational structure.

## How to fix

- Fixed in 2.34.8, 2.35.0, 2.36.0

## Technical details

The GET /api/v2/workspaces/{id}/acl endpoint checks only workspace read permission (satisfied by workspace use role) but then fetches group member data using elevated system context, bypassing RBAC. Authenticated attackers with workspace use access can enumerate all group members and their PII including email, login_type, status, created_at, and last_seen_at fields. A fix is available in versions 2.34.8 and later.
