Mailbox-secret disclosure via improper RPC access control

Published Jun 15, 2026 · Updated Jun 15, 2026

Improper access control in Huly Labs Huly Platform 0.1 through 0.7.0 allows remote authenticated users to read mailbox secrets via RPC. The CNA identifies getMailboxSecret in server/account/src/operations.ts but does not disclose which authorization decision the RPC handler performs incorrectly. A low-privileged network account can reach the operation without user interaction; the recorded consequence is limited to confidential data exposure.
