Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Github.com/loft sh/devspace, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The UI in DevSpace 4.13.0 allows web sites to execute actions on pods (on behalf of a victim) because of a lack of authentication for the WebSocket protocol. This leads to remote code execution.
