CVE-2025-68637: Apache Uniffle

Critical severity, CVSS 9.1. EPSS: 0.3% chance of exploitation in the next 30 days.

The Uniffle HTTP client is configured to trust all SSL certificates and disables hostname verification by default. This insecure configuration exposes all REST API communication between the Uniffle CLI/client and the Uniffle Coordinator service to potential Man-in-the-Middle (MITM) attacks. This issue affects all versions from before 0.10.0. Users are recommended to upgrade to version 0.10.0, which fixes the issue.

Affected products

• Apache Uniffle: before 0.10.0 (fixed in 0.10.0)
