Vulnerability Title
Flowise before 3.1.3 Remote Code Execution via Airtable Agent
Source: CVE Program / CVE List V5
Vulnerability Description
Flowise before 3.1.3 contains a code injection vulnerability in the Airtable Agent node that allows unauthenticated attackers to execute arbitrary Python code by bypassing the pythonCodeValidator blocklist through obfuscation techniques. Attackers can send crafted prompts to a chatflow using the Airtable Agent node to inject malicious Python code that executes in an unsandboxed pyodide environment with full access to the host operating system.
