CVE-2026-126404

Coder from 2.38.0 before 2.38.4 Privilege Escalation via API Key Creation

Published Nov 13, 2026 CVSS 4.0 · 7.6 High EPSS < 1% KEV · Not listed

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.
