Vulnerabilities

Flowise 3.1.2 contains an improper code generation control flaw (CWE-94, code injection) in its /api/v1/prediction/ API endpoint. A remote, unauthenticated attacker can send a crafted request to this endpoint to execute arbitrary code on the server hosting Flowise, achieving full confidentiality, integrity, and availability impact (CVSS 9.8) under the application's privileges. Only version 3.1.2 is named in the available data; the full range of affected versions and any patched release are not specified. As of the provided data, the issue is not listed in CISA's KEV and no public proof-of-concept or confirmed in-the-wild exploitation is known. The critical rating reflects that the flaw is network-reachable with no privileges or user interaction required.

Do: Inventory Flowise deployments and identify any running version 3.1.2; upgrade to a patched release as soon as the vendor publishes one (no fixed version is named in the current data), and monitor the Flowise GitHub repository for an official advisory. Until patched, restrict access to /api/v1/prediction/ by enforcing authentication, binding the service to internal interfaces, or adding reverse-proxy/firewall rules. Review logs for unexpected or unauthenticated requests to that endpoint as a sign of probing or exploitation.
