Does this matter?

Description
This affects versions of package browserless-chrome before 1.40.2-chrome-stable. User input flowing from the workspace endpoint gets used to create a file path filePath and this is fetched and then sent back to a user. This can be escaped to fetch arbitrary files from a server.
