SCA: security update for open-webui (GHSA-3vv5-8xxp-4f55)

high Tenable Cloud Security Plugin ID 443362

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior
to 0.9.6, the chat message listener allows non-same-origin input:prompt and action:submit messages, so an
external site can set prompt text and trigger submitPrompt() in an authenticated victim session. I
validated this with a cross-origin attacker page that auto-posted messages and caused unauthorized POST
/api/v1/chats/new and POST /api/chat/completions requests containing attacker-controlled prompts. This
enables cross-site forced actions and model/tool execution under victim privileges without consent. This
vulnerability is fixed in 0.9.6. (CVE-2026-54007)

Solution

Update the open-webui library and its related packages to version 0.9.6 or later.
