Answer in brief
CVE-2026-13446 records a Critical severity (CVSS 9.8) vulnerability in Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints. The current sources do not mark it as known exploited. The current feed maps IBM/Langflow OSS (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
