Apache Uniffle HTTP Client TLS Verification Bypass / MITM Exposure
CVE-2025-68637 is a critical vulnerability in Apache Uniffle affecting all versions prior to 0.10.0. The Uniffle HTTP client used by the CLI/client is configured insecurely by default to trust all SSL/TLS certificates and to disable hostname verification. As a result, REST API communications between the Uniffle CLI/client and the Uniffle Coordinator service are not properly authenticated at the TLS layer. This allows an attacker positioned on the network path to present an arbitrary certificate and impersonate the Coordinator service, enabling a man-in-the-middle attack against client-to-Coordinator traffic.
