SCA: security update for open-webui (GHSA-j2c8-v969-8r5c)

medium Tenable Cloud Security Plugin ID 443378

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, a path traversal vulnerability exists in open-webui's cache file serving endpoint that allows
any authenticated user to read files from sibling directories outside the intended cache directory, by
exploiting an incomplete startswith containment check that lacks a trailing path separator. The root cause
is that serve_cache_file() in open_webui/main.py validates the resolved path with
file_path.startswith(os.path.abspath(CACHE_DIR)) — without appending os.sep. This allows any path
resolving to a sibling directory whose name begins with cache (e.g. cache_sibling, cache_backup,
cached_models) to pass validation. This vulnerability is fixed in 0.9.6. (CVE-2026-54014)

Solution

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