Langflow: Unauthenticated Shareable Playground arbitrary local or S3 file read_CVE-2026-48520

{
    "lastseen": "",
    "description": "Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.10.0, the \"Shareable Playground\" (or \"Public Flows\" in code) contains a potential arbitrary file-read vulnerability, depending on the exact flow configuration used. By making a flow public, public execution of the flow is allowed. The execution request can contain a list of files that gets read by Langflow and fed into the LLM. The files path can be any path supported by the storage - it can be either a local file or S3 path if supported by the local configuration This vulnerability is fixed in 1.10.0.",
