{"schema":"threatline.record/2","record":{"id":"CVE-2026-101861","aliases":["GHSA-33p4-w7j3-33mw"],"summary":"Langflow Code Execution via eval() in Component Input Schema","details":"Langflow 1.0.16 before 1.12.0 and 0.0.94 before 1.12.0 contain an unsafe eval() vulnerability in schema.py that allows authenticated attackers to achieve code execution by placing a Python object with a malicious __repr__ method into component input options lists. The eval() sink is triggered when a component is converted into a LangChain tool via ComponentToolkit.get_tools(), including during custom component saves through the API, by interpolating options into a Literal type string that is passed directly to eval() without safe evaluation controls.","categories":["Applications & CMS"],"product":"langflow","vendor":"langflow-ai","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101861","source_modified_at":"2026-10-01T15:19:46.570Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"langflow","vendor":"langflow-ai","versions":[{"status":"affected","version":"1.0.16","versionType":"semver","lessThan":"1.12.0"},{"status":"affected","version":"0.0.94","versionType":"semver","lessThan":"1.12.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101861","source_modified_at":"2026-10-01T15:19:46.570Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"langflow","ecosystem":null},"version":"1.12.0","basis":"first unaffected version stated in the CVE record"}],"cvss":2.1,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00197,"percentile":0.08877,"score_date":"2026-10-23"},"published_at":"2026-09-28T15:49:14.349Z","modified_at":"2026-10-01T15:19:46.570Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-101861","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T15:19:46.570Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-101861","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/langflow-ai/langflow/security/advisories/GHSA-33p4-w7j3-33mw","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://github.com/langflow-ai/langflow/releases#release-v1.12.0","tags":["release-notes","patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-30T19:02:25.893380Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-01T15:19:46.570Z","content_hash":"8747eab14452ad1a77761b3ef5e9cfb13f983998c1ad0ad67376280908d9383e"}}
