Last modified

CVE-2026-73485 is a critical-severity vulnerability rated 9/10 on the CVSS scale. 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.. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
