Echo: snowflake-connector-python: security update to 3.18.1

critical Tenable Cloud Security Plugin ID 462492

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1
 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS
 connections made by the connector. An attacker with on-path network access could exploit this by
 intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any
 domain, causing the connector to accept connections without validating that the certificate matched the
 requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g.
 ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability
 may have exposed credentials, query data, and staged file contents to interception and tampering, and may
 have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session.
 Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake
 Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. (CVE-2026-15925)

Solution

Update the snowflake-connector-python library and its related packages to version 3.18.1 or later.
