    "summary": "# Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-w7x8-q2gp-5cgg. This link is maintained to preserve external references. # Original 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.",
