CVE-2026-126404
Coder from 2.38.0 before 2.38.4 Privilege Escalation via API Key Creation
Description
Coder 2.28.0 before 2.29.24, 2.30.0 before 2.34.16, 2.35.0 before 2.36.11, 2.37.0 before 2.37.8, and 2.38.0 before 2.38.4 does not restrict new API keys to the creating token's scopes, allow list, or expiry. A scoped API key or OAuth2 token holding key-creation permission can call POST /api/v2/users/{user}/keys/tokens to mint longer-lived coder:all keys, gaining the user's full privileges.
