# CVE-2026-110003: Azul Payara Administration REST Interface Authentication Bypass via X-GlassFish-authToken Header Leading to Remote Code Execution

Status: published. Published: 2026-11-12. Updated: 2026-11-12.

A vulnerability in the administration REST interface of Azul Payara allows a remote, unauthenticated attacker to bypass secure-admin remote-access restrictions by supplying an arbitrary value in the X-GlassFish-authToken HTTP header. The header's presence waives the remote-rejection check before the token is validated, and an invalid token falls through to password-based authentication, which succeeds without credentials on default domains configured with an empty administrative password. Successful exploitation grants execution of arbitrary administrative commands, equivalent to complete compromise of the server.
