CVE-2026-85525
Description
A flaw was found in Snowflake drivers, including Python, Go, JDBC, and Node.js. This flaw involves improper Online Certificate Status Protocol (OCSP) response validation, which allows a revoked Transport Layer Security (TLS) certificate to be accepted as valid. A man-in-the-middle attacker, possessing a revoked certificate and its private key for a Snowflake hostname, could exploit this to establish a TLS session with the driver. This would enable the attacker to read and modify data transmitted within the intercepted connection.
Statement
This vulnerability is rated as Important because improper OCSP response validation in Snowflake drivers, utilized by Red Hat OpenShift AI, could enable a man-in-the-middle attacker to intercept and modify data. Successful exploitation requires the attacker to possess a revoked TLS certificate and its corresponding private key for a Snowflake or stage hostname, along with a network position to intercept traffic, thereby limiting the attack surface.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
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.

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.
