NVD description

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, a prompt injection sent to a chatflow using a CSV Agent node can cause the LLM to respond with a malicious Python script that bypasses the blocklist validator and executes in an unsandboxed Pyodide environment. The specific flaw exists within the run method of the CSV_Agents class, where untrusted data is used to construct an LLM prompt and the resulting pythonCode is validated by validatePythonCodeForDataFrame before execution. An attacker can leverage this to execute arbitrary code in the context of the service account. This issue is fixed in 3.1.3.

    Flowise (npm) versions <= 3.1.2 ship a critical RCE in the CSV Agent node. A prompt injection in the agent input makes the LLM emit a malicious Python script that escapes the sandbox and runs arbitrary code on the host. CVE-2026-70477, GHSA-5xvg-pmgg-3mxr. Fixed in 3.1.3. https://hol.org/guard/security/cves

    Post summary

    Flowise npm versions <= 3.1.2 contain a critical RCE via prompt injection that escapes the sandbox, but the issue has been fixed in version 3.1.3.
