Answer in brief
CVE-2025-3248 records a High severity vulnerability in Langflow < 1.3.0 Unauthenticated RCE via /api/v1/validate/code. The current sources mark it as known exploited. The current feed maps langflow-ai/langflow (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.
