CVE-2026-56273

Estado: AplazadaMedia (4.9)—

Flowise before 3.1.0 contains a path traversal vulnerability in Faiss and SimpleStore vector store implementations that accept unsanitized basePath parameters from authenticated users. Attackers with valid API tokens can write vector store data to arbitrary filesystem locations, potentially enabling code execution or data exfiltration.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
