Email change-code disclosure via full-model serialization

Published Jan 5, 2026 · Updated Jan 5, 2026

Information disclosure in coolLabs Coolify 4.0.0-beta.428 and earlier allows remote authenticated users to read email change codes. TeamController.getMembers serializes complete User models from team-member queries without excluding the email_change_code field. A team account and another member with a pending email change are required; the exposed code completes that member's email change.
