CVE-2026-73487

Flowise before 3.1.3 Prompt Injection RCE via CSV Agent

Published Aug 13, 2026 CVSS 4.0 · 9 Critical EPSS < 1% KEV · Not listed
Description
Flowise before 3.1.3 contains a regex-based Python code validator bypass in CSV and Airtable Agent nodes that allows unauthenticated attackers to inject malicious code via prompt injection. Attackers can exploit unblocked pandas functions like pd.read_json() to exfiltrate datasets, perform SSRF against internal services, or achieve code execution through the unauthenticated prediction API.
