Answer in brief
CVE-2026-17633 records a High severity (CVSS 8.5) vulnerability in Langflow OSS is affected by arbitrary code execution in component generation, validation, and custom component handling. 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 8.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
