Overview

CVE-2026-42283 is a high-severity vulnerability. It was published on May 14, 2026 and has a CVSS 3.1 base score of 7.7 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.7, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

DevSpace is a client-only developer tool for cloud-native development with Kubernetes. Prior to 6.3.21, DevSpace's UI server WebSocket accepts connections from all origins by default, and therefore several endpoints are exposed via this WebSocket. When a developer runs the DevSpace UI and at the same time uses a browser to access the internet, a malicious website they visit can use their browser to establish a cross-origin WebSocket connection to ws://127.0.0.1:8090. This vulnerability is fixed in 6.3.21.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
