CVE-2026-15925

Description

A flaw was found in Snowflake Connector for Python. A network-positioned attacker could exploit improper Transport Layer Security (TLS) hostname verification by intercepting network traffic and presenting a fraudulent certificate. This could allow the attacker to bypass certificate hostname validation, leading to the acceptance of connections without proper verification. Consequently, this vulnerability may expose sensitive credentials and query data to interception and tampering, and could enable the attacker to execute arbitrary SQL commands within the victim's session.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)

Integrity,Authentication

Technical Impact: Bypass Protection Mechanism; Gain Privileges or Assume Identity

When a certificate is invalid or malicious, it might allow an attacker to spoof a trusted entity by interfering in the communication path between the host and client. The product might connect to a malicious host while believing it is a trusted host, or the product might be deceived into accepting spoofed data that appears to originate from a trusted host.
