CVE-2026-69255 Flowise: CSV Agent Remote Code Execution via Pyodide Code Injection — Root Shell Verified

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the CSVAgent in packages/components/nodes/agents/CSVAgent/CSVAgent.ts extracted attacker-controlled CSV data with file.split','.pop and interpolated it directly into executable Python as...

CVE-2026-69256: Improper Control of Generation of Code

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the CSVAgent node allowed users to provide Python code that is executed through pyodide; although a denylist blocked dangerous Python constructs, pandas.readpickle could deserialize a pickled...

CVE-2026-69264: Improper Control of Generation of Code

Prior to 3.1.3, Flowise CSVAgent interpolates an attacker-controlled segment of the csvFile data URI directly into a Python source-code template that is then executed by Pyodide. Because Pyodide is loaded with the default js bridge to globalThis, which on Node.js exposes eval and dynamic import,...
