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."}], "lastModified": "2026-06-26T17:07:36.970", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:langflow:langflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F5488C0C-98DB-4686-808B-99CB766D514C", "versionEndExcluding": "1.9.2"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
