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-2026-105698 exists.\n\nAffected packages and fixed versions:\n- langflow (PyPI): affected from 1.0.0; fixed in 1.10.1\n- langflow (PyPI): affected from 1.0.0; fixed in 1.10.1\n- langflow (PyPI): affected from 1.0.0; fixed in 1.10.1\n- langflow-base (PyPI): affected all versions; fixed in 0.10.1\n- langflow-base (PyPI): affected all versions; fixed in 0.10.1\n- langflow-base (PyPI): affected all versions; fixed in 0.10.1\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-2026-105698/ (Markdown: https://insights.sbomify.com/CVE-2026-105698/index.md)","id":"CVE-2026-105698","markdown":"https://insights.sbomify.com/CVE-2026-105698/index.md","name":"CVE-2026-105698","record":{"aliases":["GHSA-gh98-4phw-6fmw","PYSEC-2026-4234","PYSEC-2026-4238"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"AI workflow builder","requires_auth":"low_privilege","summary":"Attackers can access private AI workflows and execute vertices without proper ownership checks, leading to data disclosure and unauthorized code execution.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Langflow is a tool for building and deploying AI-powered agents and workflows. From 1.0.0 until 1.10.1, Langflow did not verify flow ownership in the deprecated POST /api/v1/build/{flow_id}/vertices and POST /api/v1/build/{flow_id}/vertices/{vertex_id} handlers. Through version 1.7.1, an unauthenticated caller who knew another user's flow UUID could reach these handlers; from version 1.7.2 through 1.10.0, callers had to authenticate but needed no elevated privileges. Such a caller could cause retrieve_vertices_order to load and cache the private graph, enumerate its vertex identifiers, and use build_vertex to execute selected vertices and receive their results. build_graph_from_db_no_cache performed a primary-key lookup without an owner filter. This could disclose private flow structure, configured values, and selected outputs and could trigger victim-configured side effects and build-history records, although it did not expose the victim's variable-store credentials or permit modification of the stored flow. This issue is fixed in Langflow 1.10.1 and langflow-base 0.10.1.","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":"Langflow: Cross-user flow access and vertex execution via deprecated /api/v1/build/{flow_id}/vertices endpoints","id":"CVE-2026-105698","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":6,"n_references":4,"next":{"headline":"Langflow: Authenticated Cross-Project File Disclosure via Unscoped MCP Resource Handlers","id":"CVE-2026-105699"},"packages":[{"ecosystem":"PyPI","fixed":["1.10.1"],"introduced":["1.0.0"],"last_affected":[],"package":"langflow","purl":null,"source":"GHSA-gh98-4phw-6fmw"},{"ecosystem":"PyPI","fixed":["1.10.1"],"introduced":["1.0.0"],"last_affected":[],"package":"langflow","purl":"pkg:pypi/langflow","source":"GHSA-gh98-4phw-6fmw"},{"ecosystem":"PyPI","fixed":["1.10.1"],"introduced":["1.0.0"],"last_affected":[],"package":"langflow","purl":"pkg:pypi/langflow","source":"PYSEC-2026-4234"},{"ecosystem":"PyPI","fixed":["0.10.1"],"introduced":["0"],"last_affected":[],"package":"langflow-base","purl":null,"source":"GHSA-gh98-4phw-6fmw"},{"ecosystem":"PyPI","fixed":["0.10.1"],"introduced":["0"],"last_affected":[],"package":"langflow-base","purl":"pkg:pypi/langflow-base","source":"GHSA-gh98-4phw-6fmw"},{"ecosystem":"PyPI","fixed":["0.10.1"],"introduced":["0"],"last_affected":[],"package":"langflow-base","purl":"pkg:pypi/langflow-base","source":"PYSEC-2026-4238"}],"prev":{"headline":"Langflow: OS command injection (RCE) via arbitrary command in MCP stdio server configuration","id":"CVE-2026-105697"},"products":["langflow","langflow-base"],"published":"2026-10-05","related":[],"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":"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":"2026-10-06","vendors":["langflow-ai"]},"summary":"Attackers can access private AI workflows and execute vertices without proper ownership checks, leading to data disclosure and unauthorized code execution.","url":"https://insights.sbomify.com/CVE-2026-105698/"}
