What it is

A security check relies on a value the attacker can set.

How it is reached

An attacker can exploit it over the network, without an account, and nobody has to click anything.

What an attacker gains

A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker reach data or actions their role should not allow.

Is it being exploited?

There is no public report of exploitation yet.

What to do

  1. Upgrade Azul Payara Payara Server to a fixed version for your release line (7.6.0, 7.2026.11, 6.44.0). Other affected products have their own fixed versions on this page.
  2. Until it is patched, keep it off the internet or behind a VPN, allowlist or authenticating proxy.

Description from NVD

A vulnerability in the GenericAdminAuthenticator component of Azul Payara Server and Azul Payara Micro allows a remote, unauthenticated attacker to bypass JMX/RMI administrative access restrictions by spoofing the client host address. Successful exploitation can grant administrative access to the MBean server and lead to remote code execution. Azul Payara Micro is affected only when its JMX connector is enabled.

What this means for your architecture.

A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.

Components it touches

  • Permission checks in APIs and admin surfaces. The flaw sits between one role or tenant and another.
  • Multi-tenant services. The flaw sits between one role or tenant and another.

Trust boundaries in play

  • Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
  • Between one role or tenant and another. An attacker who crosses it can reach data or actions their role should not allow.

Questions to answer about your own systems

  • Where does Azul Payara Payara Server run in your systems, and at which version?
  • Which of those instances can be reached from the internet or partner networks?
  • What can it reach once compromised: which data stores, secrets and services?
