## Overview

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, channel thread parent and reply handling did not bind parent_id to the channel in the URL, allowing an authenticated user to reference a message from another private or DM channel and disclose thread context across channels. This issue is fixed in version 0.10.0.

## Affected

- `open_webui < 0.10.0`

## Remediation

Upgrade past the affected range:

- `open_webui 0.10.0`
