CRITICAL 9.1

DescriptionNVD

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.

AnalysisAI

Uniffle HTTP client (before 0.10.0) trusts all SSL certificates and disables hostname verification by default, exposing all REST API communication between the CLI and Coordinator to man-in-the-middle attacks.

Technical ContextAI

The HTTP client is configured to trust all certificates and skip hostname verification (CWE-297). This means any network attacker can intercept, read, and modify all API communication between the Uniffle CLI and Coordinator without triggering any warnings.

RemediationAI

Update to Uniffle 0.10.0 or later. Verify that SSL verification is enabled after updating.
