It then extracts a one-line lambda from the model response, applies only syntactic format checks, evaluates it with Python's full builtins, and invokes the resulting function inside the Langflow process.\n\nA malicious flow author can exploit this directly through the Instructions field. In deployments where an exposed flow passes attacker-controlled content into Smart Transform, an attacker may also exploit it indirectly through prompt injection, subject to the configured model following the injected instruction.\n\n## Vulnerability details\n\n**Vulnerable Code Location**: `src/lfx/src/lfx/components/llm_operations/lambda_filter.py` (line 242 in v1.10.2)\n\n```python\ndef _validate_lambda(self, lambda_text: str) -> bool:\n    \"\"\"Validate the provided lambda function text.\"\"\"\n    return lambda_text.strip().startswith(\"lambda\") and \":\" in lambda_text\n\n# ...\nreturn eval(lambda_text)  # noqa: S307\n```\n\nFor examp","public_affected_ranges":[">= 1.3.0, < 1.10.3"]}],"null_published_at":"2026-11-01T07:29:12.910Z","source_updated_at":"2026-10-05T22:30:42.000Z","source_disclosed_at":"2026-10-05T22:30:41.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-01T01:39:10.636Z"}],"next_cursor":null,"snapshot_revision":"42594"}
