# Homer: Complete Authentication Bypass When coordinator.jwt.secret Is Empty (Default) in github.com/sipcapture/homer-app

Homer (github.com/sipcapture/homer-app), a SIP monitoring web app, accepts forged authentication tokens when coordinator.jwt.secret is left empty, which is the default. An attacker can bypass login entirely and gain full access to the application.

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

## Affected

- go:github.com/sipcapture/homer-app affected all versions fixed ?

## How to check

Check the Homer config for coordinator.jwt.secret and confirm it is set to a non-empty value.

## Fix

Set coordinator.jwt.secret to a long random non-empty value and upgrade homer-app to a version at or after v0.0.0-20260625093330-5e90809657c9 (the advisory's fixed pseudo-version; the sources do not name a semver tag).
