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-2026-59216 exists.\n\nAffected packages and fixed versions:\n- open-webui (PyPI): affected all versions; fixed in 0.10.0\n- open-webui (PyPI): affected all versions; fixed in 0.10.0\n- open-webui (PyPI): affected all versions; fixed in 0.10.0\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-2026-59216/ (Markdown: https://insights.sbomify.com/CVE-2026-59216/index.md)","id":"CVE-2026-59216","markdown":"https://insights.sbomify.com/CVE-2026-59216/index.md","name":"CVE-2026-59216","record":{"aliases":["GHSA-74h3-cxq7-vc5q","PYSEC-2026-3592"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Open WebUI AI platform","requires_auth":"low_privilege","summary":"Authenticated users can execute Python code or tools in other users' sessions by exploiting unvalidated Socket.IO session IDs, leading to cross-user code execution.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"open_webui","vendor":"openwebui"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform.
