CVE-2026-45387
CVE-2026-45387 · Open WebUI: Sharing models for others to use (read permission) also exposes model details (system prompt leakage)
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, when setting model permissions so that a group has read access to it, intending for other users to use it, those users also can read the model's system prompt. However users may consider their system prompt confidential, so this is considered a security issue. This vulnerability is fixed in 0.9.5.
