Routine

HIGH 8.1

CVE-2026-19594 is a high-severity flaw (CVSS 8.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Insufficient input sanitization in Snowflake Python API (`snowflake.core`) versions prior to 1.13.0 allowed confused-deputy privilege escalation through two related weaknesses: path traversal (CWE-22) via unencoded `..` identifier path segments, and HTTP parameter pollution (CWE-141) via unencoded `&`/`#`/`=` characters in query string values. An attacker with access to a downstream application built on snowflake.core could exploit the path trave

Why this priority

High severity

A fixed release or distro patch exists.
