{"id":"CVE-2026-48519","state":"PUBLISHED","title":"Langflow: Unauthenticated RCE in Shareable Playgrounds","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.","publishedAt":"2026-06-23T16:25:09.927Z","updatedAt":"2026-06-24T03:56:21.994Z","severity":{"score":9.6,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["langflow-ai langflow"],"affected":[{"vendor":"langflow-ai","product":"langflow","versions":[{"version":"< 1.9.2","status":"affected"}]}],"references":["https://github.com/langflow-ai/langflow/security/advisories/GHSA-v5ff-9q35-q26f"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/48xxx/CVE-2026-48519.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-48519","state":"PUBLISHED","datePublished":"2026-06-23T16:25:09.927Z","dateUpdated":"2026-06-24T03:56:21.994Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-21T16:18:10.619Z"},"containers":{"cna":{"title":"Langflow: Unauthenticated RCE in Shareable Playgrounds","descriptions":[{"lang":"en","value":"Langflow is a tool for building and deploying AI-powered agents and workflows.
