CVE-2026-44206Network attack vector

Unauthenticated schema disclosure via header-controlled DocType lookup

Published Jun 12, 2026 · Updated Jun 12, 2026

Information disclosure in Frappe Framework 15.x before 15.107.2 and 16.x before 16.17.4 allows remote attackers to enumerate database schema. The validate_api_key_secret function trusts the Frappe-Authorization-Source header as the DocType for a database lookup and exposes distinguishable lookup failures. No authentication or user interaction is required; disclosure is limited to schema information, with no reported data modification or service interruption.
