Summary

DevSpace UI Server WebSocket CheckOrigin does not validate source

Details

Description

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 allows an attacker to access: * /api/logs to stream real-time pod logs * /api/enter to open an interactive shell inside the running pod * /api/command to execute pre-defined pipeline commands

Patches

Versions 6.3.21 and above are patched.

CVE-2026-42283 (GCVE-0-2026-42283)

Vulnerability from cvelistv5 – Published: 2026-05-14 15:44 – Updated: 2026-05-16 00:36

Title

DevSpace UI Server WebSocket CheckOrigin does not validate source

Summary

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.

Severity

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
