What is CVE-2025-68637?

The Uniffle HTTP Client is improperly configured to trust all SSL certificates and disables hostname verification by default. This insecure setup leaves REST API communications vulnerable to potential Man-in-the-Middle (MITM) attacks, allowing malicious actors to intercept or alter data between the Uniffle CLI/client and the Uniffle Coordinator service. To mitigate this risk, all users are strongly advised to upgrade to version 0.10.0, which addresses this configuration flaw.

Affected Version(s)

Apache Uniffle 0 < 0.10.0
