# taOS: any logged-in user can read and change system settings

Link for people: https://infrastack.ai/live/CVE-2026-67548 (this .md is for agents)

taOS is a self-hosted AI agent OS whose system settings routes lack any admin check. Any authenticated user, including non-admin invited users, can read the full configuration, overwrite it, and trigger an update and service restart, causing denial of service for everyone on the instance.

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

## Affected

- vendor:taOS affected range not listed fixed no fixed version listed

## How to check

- Check the installed taOS version and whether it is below `1.0.0-beta.25`
- Confirm whether non-admin invited accounts exist on the instance

## Fix

- taOS: upgrade to `1.0.0-beta.25`

## From the sources

taOS is a self-hosted AI agent OS. Prior to version 1.0.0-beta.25, tinyagentos (taOS) registers all system settings routes under a single APIRouter() instance created with no admin authorization dependency. Any authenticated user—including non-admin invited users whose is_admin flag is explicitly False—can read the full system configuration, overwrite it, modify platform settings, trigger a git pull + dependency reinstall + service restart, and switch the tracked update branch. Successful exploitation of the write endpoints causes immediate configuration corruption or a denial of service for all users on the instance from a low-privileged account. This issue has been patched in version 1.0.0-beta.25.
