Especially if the server is exposed on the network by `browser.api.host: true`, an attacker can send a request to that handler from remote to get the content of arbitrary files.This `__screenshot-error` handler on the browser mode HTTP server responds any file on the file system. This code was added by commit `2d62051`. Users explicitly exposing the browser mode server to the network by `browser.api.host: true` may get any files exposed. This issue has been addressed in versions 2.1.9 and 3.0.4. Users are advised to upgrade. There are no known workarounds for this vulnerability.
