CVE-2025-48056

Hubble CLI vulnerable to character injection

Published May 20, 2025 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
Hubble is a fully distributed networking and security observability platform for cloud native workloads. Prior to version 1.17.2, a network attacker could inject malicious control characters into Hubble CLI terminal output, potentially leading to loss of integrity and manipulation of the output. This could be leveraged to conceal log entries, rewrite output, or even make the terminal temporarily unusable. Exploitation of this attack would require the victim to be monitoring Kafka traffic using Layer 7 Protocol Visibility at the time of the attack. The issue is patched in Hubble CLI v1.17.2. Hubble CLI users who are unable to upgrade can direct their Hubble flows to a log file and inspect the output within a text editor.
