| Title | open-webui 6.16 Use of Hard-coded Cryptographic Key |
|---|
| Description | https://github.com/open-webui/open-webui/blob/4770285c04b81dfc3eb9ac173dfb2a8afef68105/backend/start_windows.bat#L27，In the script
By default%WEBUI_SECRET_KEY%%WEBUI_JWT_SECRET_KEY%is equal to""instead of" ". Therefore, in a Windows environment, when using start_windows.bat to start open-webui, a random JWT_SECRET_KEY cannot be generated correctly, but rather a hard coded one. This situation may be vulnerable to JWT forgery attacks |
