# AxxonNet: shared read-only report token can change monitoring alerts

AxxonNet's Health Monitoring service on Linux, before version 3.28.0, does not check permissions properly for a shared report token that is meant to be read-only. A remote attacker holding such a token can create, change or delete monitoring alerts through the monitoring API.

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

## How to check

- Check the installed AxxonNet version on Linux hosts; the sources do not give a command.
- Look for shared report tokens in use and whether the monitoring API is reachable from outside the network.

## Fix

- AxxonNet `3.28.0` or later, per the sources' 'before 3.28.0' range.

## Timeline

- 2026-11-03T09:19:51+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-121024

## From the sources

Incorrect Authorization (CWE-863) in the Health Monitoring service in AxxonSoft AxxonNet before 3.28.0 on Linux allows a remote attacker in possession of a shared report token, which is intended for read-only access, to create, modify or delete monitoring alerts via the monitoring API.
