# Java application server: unauthenticated remote deployment of arbitrary applications

Link for people: https://infrastack.ai/live/CVE-2026-87756 (this .md is for agents)

Internal system EJBs used for remote deployment and configuration skip their administrative role check when the server runs with the default profile. A remote attacker who can reach the EJB endpoint can deploy arbitrary applications and execute code.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the server has the system applications and a remote EJB endpoint enabled; the sources do not name the setting or file.
- The sources do not name the product or version range, so confirm the product and version from the NVD entry.

## Fix

- Upgrade to `10.3.0` or `11.0.0-M2`, the versions the description gives; the product line is not named.

## From the sources

The internal system EJBs used for remote deployment and configuration did not enforce their administrative role check when the server ran with the default profile. A remote unauthenticated attacker able to reach the remote EJB endpoint could deploy arbitrary applications and execute code. Only installations that enabled the system applications and a remote EJB endpoint are exposed. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
