SCA: security update for open-webui (GHSA-4r4w-2wgp-w7cj)

medium Tenable Self-Hosted Container Security Plugin ID 443353

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, Open WebUI's prompt version-history endpoints authorize the prompt_id in the URL but then act on
 caller-supplied history IDs without verifying that the history row belongs to that prompt
 (history_entry.prompt_id == prompt.id). This affects /api/v1/prompts/id/{prompt_id}/history/diff,
 /api/v1/prompts/id/{prompt_id}/update/version, and /api/v1/prompts/id/{prompt_id}/history/{history_id}. An
 authenticated user with access to any prompt they control, plus a victim prompt_history.id, can read or
 delete another user's private prompt history. This vulnerability is fixed in 0.9.6. (CVE-2026-54015)

Solution

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