Google and Mozilla are working together on a method to let web apps gain access to users' files.

A group led by Google and Mozilla is working to make it easy to edit files using browser-based web apps but wants advice on how to guard against the "major" security and privacy risks.

The idea is to allow users to save changes they've made using web apps, without the hassle of having to download new files after each edit, as is necessary today.

[...] the W3C Web Incubator Community Group (WICG), which is chaired by representatives from Chrome developer Google and Firefox developer Mozilla, is working on developing the new Writable Files API, which would allow web apps running in the browser to open a file, edit it, and save the changes back to the same file.

However, the group says the biggest challenge will be guarding against malicious sites seeking to abuse persistent access to files on a user's system.

"By far the hardest part for this API is of course going to be the security model to use," warns the WICG's explainer page for the API.

"The API provides a lot of scary power to websites that could be abused in many terrible ways.

What could possibly go wrong?

    In summary, if they don't science the shit out of this user file access idea, users will have to sandbox the shit out of the browsers.

    Probably should've been sandboxing browsers all along anyway.

    With recent exploits no sandboxing is safe.

      Or only buy computers capable of running registered memory.

      And that is ignoring the speculative execution and other timing/race leaks in modern processors.

      Very little hardware can be considered secure from either hackers or state level adversaries largely because of the commercial limitations of available consumer electronics.
