Versions of webpack-dev-server before 3.1.10 are missing origin validation on the websocket server. This vulnerability allows a remote attacker to steal a developer’s source code because the origin of requests to the websocket server that is used for Hot Module Replacement (HMR) are not validated.
Recommendation
For webpack-dev-server update to version 3.1.11 or later.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| webpack-dev-server | lt | 3.1.11 |
