CVE-2025-68637Network attack vector

REST API interception via trust-all TLS client

Published Jan 7, 2026 · Updated Jan 7, 2026

Improper certificate validation in Apache Uniffle before 0.10.0 allows man-in-the-middle attackers to read or alter REST API traffic. The Uniffle HTTP client accepts every server certificate and disables hostname matching by default when connecting the CLI or client to the Coordinator. An attacker able to intercept that network path can impersonate the Coordinator and observe or modify its REST API exchanges.
