{"cve":"CVE-2026-48519","nvd":{"published":"2026-06-23T17:17:01.240","modified":"2026-10-26T11:10:00.157","status":"Analyzed","description":"Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.2, the \"Shareable Playground\" (or \"Public Flows\" in code) contains a critical RCE vulnerability. Shareable Playground feature works by enabling the execution of workflows by unauthenticated users, by accessing a link. Specifically, it enables the route /api/v1/build_public_tmp to execute any public flow, given a public flow ID. When the route executes the flow, it allows for providing arbitrary custom Python code as the nodes code, inside the JSON payload. The vulnerable field is data.nodes[X].data.node.template.code.value. This vulnerability is fixed in 1.9.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-94"],"references":["https://github.com/langflow-ai/langflow/security/advisories/GHSA-v5ff-9q35-q26f","https://github.com/langflow-ai/langflow/security/advisories/GHSA-v5ff-9q35-q26f"],"products":["langflow:langflow"],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-48519","score":0.00783,"percentile":0.55743,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v5ff-9q35-q26f","url":"https://osv.dev/vulnerability/GHSA-v5ff-9q35-q26f","summary":"Langflow: Unauthenticated RCE in Shareable Playgrounds","modified":"2026-07-20T14:00:25.686242559Z","packages":[{"ecosystem":"PyPI","name":"langflow","purl":"pkg:pypi/langflow","ranges":["<1.9.2"],"fixed":["1.9.2"]}]},{"id":"PYSEC-2026-243","url":"https://osv.dev/vulnerability/PYSEC-2026-243","summary":"","modified":"2026-06-27T11:15:05.223546160Z","packages":[{"ecosystem":"PyPI","name":"langflow","purl":"pkg:pypi/langflow","ranges":["<1.9.2"],"fixed":["1.9.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
