Description

### Impact When following HTTP redirects, `net.fetch()` and `net.request()` did not restrict which schemes a redirect could target. A remote server could redirect a request to a local resource, and if the app returns or forwards the response body, local file contents could be disclosed. Apps are only affected if they make `net` requests to attacker-influenced URLs with redirects followed (the default) and expose the response body. Apps that only request fixed, trusted URLs are not affected. ### Workarounds Set `redirect: 'error'` or `redirect: 'manual'` on requests to untrusted URLs and validate any redirect target before following it. ### Fixed Versions * `42.0.0-beta.3` * `41.2.1` * `40.9.0` * `39.8.8` ### For more information If you have any questions or comments about this advisory, email Electron at [security@electronjs.org](mailto:security@electronjs.org)
