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-2025-64496 exists.\n\nAffected packages and fixed versions:\n- open-webui (PyPI): affected all versions; fixed in 0.6.35\n- open-webui (PyPI): affected all versions; fixed in 0.6.35\n- open-webui (PyPI): affected all versions; fixed in 0.6.35\n- open-webui (npm): affected all versions; fixed in 0.6.35\n- open-webui (npm): affected all versions; fixed in 0.6.35\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-2025-64496/ (Markdown: https://insights.sbomify.com/CVE-2025-64496/index.md)","id":"CVE-2025-64496","markdown":"https://insights.sbomify.com/CVE-2025-64496/index.md","name":"CVE-2025-64496","record":{"aliases":["GHSA-cm35-v4vp-5xvx","PYSEC-2026-1729"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"AI platform","requires_auth":"low_privilege","summary":"Malicious model servers can inject JavaScript via SSE events in Open WebUI, leading to account takeover and potential backend code execution.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"open_webui","vendor":"openwebui"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-95","name":"Improper Neutralization of Directives in Dynamically Evaluated Code"},{"id":"CWE-830","name":"Inclusion of Web Functionality from an Untrusted Source"},{"id":"CWE-829","name":"Inclusion of Functionality from Untrusted Control Sphere"},{"id":"CWE-501","name":"Trust Boundary Violation"}],"description":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Versions 0.6.224 and prior contain a code injection vulnerability in the Direct Connections feature that allows malicious external model servers to execute arbitrary JavaScript in victim browsers via Server-Sent Event (SSE) execute events. This leads to authentication token theft, complete account takeover, and when chained with the Functions API, enables remote code execution on the backend server. The attack requires the victim to enable Direct Connections (disabled by default) and add the attacker's malicious model URL, achievable through social engineering of the admin and subsequent users. This issue is fixed in version 0.6.35.","ecosystems":["PyPI","npm"],"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 Affected by an External Model Server (Direct Connections) Code Injection via SSE Events","id":"CVE-2025-64496","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"openwebui:open_webui","products":["openwebui:open_webui"],"type":"code_injection","year":"2025"},"n_packages":5,"n_references":2,"next":{"headline":"Tuleap exposes releases for all projects to File Release System project administrators","id":"CVE-2025-64497"},"packages":[{"ecosystem":"PyPI","fixed":["0.6.35"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":null,"source":"GHSA-cm35-v4vp-5xvx"},{"ecosystem":"PyPI","fixed":["0.6.35"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":"pkg:pypi/open-webui","source":"GHSA-cm35-v4vp-5xvx"},{"ecosystem":"PyPI","fixed":["0.6.35"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":"pkg:pypi/open-webui","source":"PYSEC-2026-1729"},{"ecosystem":"npm","fixed":["0.6.35"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":null,"source":"GHSA-cm35-v4vp-5xvx"},{"ecosystem":"npm","fixed":["0.6.35"],"introduced":["0"],"last_affected":[],"package":"open-webui","purl":"pkg:npm/open-webui","source":"GHSA-cm35-v4vp-5xvx"}],"prev":{"headline":"Open WebUI vulnerable to Stored DOM XSS via prompts when 'Insert Prompt as Rich Text' is enabled resulting in ATO/RCE","id":"CVE-2025-64495"},"products":["open-webui"],"published":"2025-11-08","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":"total"},"state":"PUBLISHED","updated":"2025-11-13","vendors":["open-webui"]},"summary":"Malicious model servers can inject JavaScript via SSE events in Open WebUI, leading to account takeover and potential backend code execution.","url":"https://insights.sbomify.com/CVE-2025-64496/"}
