Last modified
CVE-2026-73486 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. Flowise before 3.1.3 contains a code injection vulnerability in the CSV Agent node's customReadCSV parameter that allows authenticated attackers to execute arbitrary Python code. The validator uses a static regex blocklist that can be bypassed through obfuscation techniques, enabling attackers to execute code in the unsandboxed pyodide environment with full system access.. EPSS estimates a 0.33% chance of exploitation in the next 30 days.
