CVE-2026-59222 Details
Description
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.7.0 before 0.10.0, GET /api/v1/channels//members returned full UserModelResponse objects for channel members, including settings.ui.toolServers[].key and webhook configuration, allowing a normal channel participant to retrieve other users’ sensitive settings. This issue is fixed in version 0.10.0.
A vulnerability in Open WebUI versions 0.7.0 prior to 0.10.0 allows normal channel participants to access sensitive user settings through the channel members API. The API response includes full user model details, such as admin-only webhook URLs and tool server keys, which are not available through standard user profile endpoints. This issue arises because the channel members endpoint serializes and returns complete user models, including private settings, to all channel members.
Users can update to Open WebUI version 0.10.0 or later, where this vulnerability has been fixed.
