Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-54014 exists.\n\nAffected packages and fixed versions:\n- open-webui (PyPI): affected all versions; fixed in 0.9.6\n- open-webui (PyPI): affected all versions; fixed in 0.9.6\n- open-webui (PyPI): affected all versions; fixed in 0.9.6\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-54014/ (Markdown: https://insights.sbomify.com/CVE-2026-54014/index.md)","id":"CVE-2026-54014","markdown":"https://insights.sbomify.com/CVE-2026-54014/index.md","name":"CVE-2026-54014","record":{"aliases":["GHSA-j2c8-v969-8r5c","PYSEC-2026-2736"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Open WebUI","requires_auth":"low_privilege","summary":"Authenticated users can read files from sibling directories outside the cache directory due to a path traversal flaw in Open WebUI.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"open_webui","vendor":"openwebui"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"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.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Open WebUI: Sibling-Prefix Path Traversal via /cache/{path} in open-webui/open-webui","id":"CVE-2026-54014","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"openwebui:open_webui","products":["openwebui:open_webui"],"type":"path_traversal","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"Open WebUI: Prompt history IDOR: unbound history_id allows cross-prompt read and deletion","id":"CVE-2026-54015"},"packages":[{"ecosystem":"PyPI","fixed":["0.9.6"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":null,"source":"GHSA-j2c8-v969-8r5c"},{"ecosystem":"PyPI","fixed":["0.9.6"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":"pkg:pypi/open-webui","source":"GHSA-j2c8-v969-8r5c"},{"ecosystem":"PyPI","fixed":["0.9.6"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":"pkg:pypi/open-webui","source":"PYSEC-2026-2736"}],"prev":{"headline":"Open WebUI: Stored XSS to Account Takeover via Model Profile Images in Open WebUI","id":"CVE-2026-54013"},"products":["open-webui"],"published":"2026-06-23","related":[{"cvss_score":9.1,"headline":"Open WebUI: LDAP Empty Password Authentication Bypass","id":"CVE-2026-44551","kev_date_added":null,"published":"2026-05-15"},{"cvss_score":9,"headline":"open-webui - Remote Code Execution via CORS Misconfiguration and Session Validation","id":"CVE-2026-56400","kev_date_added":null,"published":"2026-07-15"},{"cvss_score":9,"headline":"Cross-site Scripting (XSS) in open-webui/open-webui","id":"CVE-2024-8017","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":8.8,"headline":"Open WebUI: Jupyter code execution works despite `ENABLE_CODE_EXECUTION=false` — feature gate bypassed","id":"CVE-2026-45672","kev_date_added":null,"published":"2026-05-15"},{"cvss_score":8.7,"headline":"Open WebUI: Same-origin XSS to account takeover via terminal port-preview iframe hardcoding allow-same-origin","id":"CVE-2026-87995","kev_date_added":null,"published":"2026-09-09"},{"cvss_score":8.7,"headline":"Open WebUI: Stored XSS via unescaped KaTeX render-error fallback in rendered messages","id":"CVE-2026-70492","kev_date_added":null,"published":"2026-08-04"},{"cvss_score":8.7,"headline":"Open WebUI: Stored XSS in Mermaid Markdown Preview","id":"CVE-2026-54011","kev_date_added":null,"published":"2026-06-23"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-24","vendors":["open-webui"]},"summary":"Authenticated users can read files from sibling directories outside the cache directory due to a path traversal flaw in Open WebUI.","url":"https://insights.sbomify.com/CVE-2026-54014/"}
