Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-46571 exists.\n\nAffected packages and fixed versions:\n- open-webui (PyPI): affected all versions; fixed in 0.6.6\n- open-webui (PyPI): affected all versions; fixed in 0.6.6\n- open-webui (PyPI): affected all versions; fixed in 0.6.6\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-2025-46571/ (Markdown: https://insights.sbomify.com/CVE-2025-46571/index.md)","id":"CVE-2025-46571","markdown":"https://insights.sbomify.com/CVE-2025-46571/index.md","name":"CVE-2025-46571","record":{"aliases":["GHSA-8gh5-qqh8-hq3x","PYSEC-2026-2713"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"AI platform","requires_auth":"low_privilege","summary":"Low-privileged users can upload malicious HTML files to trigger stored XSS, potentially leading to admin account takeover and remote code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"open_webui","vendor":"openwebui"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H/E:P","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to version 0.6.6, low privileged users can upload HTML files which contain JavaScript code via the `/api/v1/files/` backend endpoint. This endpoint returns a file id, which can be used to open the file in the browser and trigger the JavaScript code in the user's browser. Under the default settings, files uploaded by low-privileged users can only be viewed by admins or themselves, limiting the impact of this vulnerability. A link to such a file can be sent to an admin, and if clicked, will give the low-privileged user complete control over the admin's account, ultimately enabling RCE via functions. Version 0.6.6 contains a fix for the issue.","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 vulnerable to limited stored XSS vila uploaded html file","id":"CVE-2025-46571","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"openwebui:open_webui","products":["openwebui:open_webui"],"type":"xss","year":"2025"},"n_packages":3,"n_references":3,"next":{"headline":"passport-wsfed-saml2 Has SAML Authentication Bypass via Signature Wrapping","id":"CVE-2025-46572"},"packages":[{"ecosystem":"PyPI","fixed":["0.6.6"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":null,"source":"GHSA-8gh5-qqh8-hq3x"},{"ecosystem":"PyPI","fixed":["0.6.6"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":"pkg:pypi/open-webui","source":"GHSA-8gh5-qqh8-hq3x"},{"ecosystem":"PyPI","fixed":["0.6.6"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":"pkg:pypi/open-webui","source":"PYSEC-2026-2713"}],"prev":{"headline":"vLLM’s Chunk-Based Prefix Caching Vulnerable to Potential Timing Side-Channel","id":"CVE-2025-46570"},"products":["open-webui"],"published":"2025-05-05","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":"2025-05-05","vendors":["open-webui"]},"summary":"Low-privileged users can upload malicious HTML files to trigger stored XSS, potentially leading to admin account takeover and remote code execution.","url":"https://insights.sbomify.com/CVE-2025-46571/"}
