CVE-2026-13380Network attack vector

Unauthenticated SFTP credential disclosure via HTTP responses

Published Jul 20, 2026 · Updated Jul 20, 2026

Credential disclosure in VSee Clinic 7.1.26 and VSee Clinic API 1.3.0 allows remote attackers to obtain SFTP credentials via HTTP responses. Three unauthenticated endpoints include configured SFTP credentials in their response bodies instead of withholding sensitive connection data. The exposure exists only when SFTP is configured, and the disclosed credentials grant access to the associated SFTP server.
