CVE-2026-90450 MEDIUM

Published: 2026-09-11 | Last Modified: 2026-09-11 | Status: Received

Description

The application's role-authorization lookup defaults to granting access when a request handler's name is not present in its table of role requirements, rather than defaulting to deny. Any request handler that is not explicitly registered in this table is reachable by any authenticated user regardless of their assigned role, and any newly added handler is fail-open by default until explicitly added to the table.
