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-2025-64495 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-2025-64495/ (Markdown: https://insights.sbomify.com/CVE-2025-64495/index.md)","id":"CVE-2025-64495","markdown":"https://insights.sbomify.com/CVE-2025-64495/index.md","name":"CVE-2025-64495","record":{"aliases":["GHSA-w7xj-8fx7-wfch","PYSEC-2026-1741"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"AI chat platform","requires_auth":"low_privilege","summary":"Stored DOM XSS in Open WebUI allows attackers to execute arbitrary code or take over accounts via malicious prompts when rich text insertion is enabled.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"open_webui","vendor":"openwebui"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"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.
