Summary: Provide a catchall mechanism to find unprotected writes. - Depends on D758. - Similar to WriteOnHTTPGet stuff from Facebook's stack. - Since we have a small number of storage mechanisms and highly structured read/write pathways, we can explicitly answer the question "is this page performing a write?". - Never allow writes without CSRF checks. - This will probably break some things. That's fine: they're CSRF vulnerabilities or weird edge cases that we can fix. But don't push to Facebook for a few days unless you're prepared to deal with this. - **>>> MEGADERP: All Conduit write APIs are currently vulnerable to CSRF! <<<** Test Plan: - Ran some scripts that perform writes (scripts/search indexers), no issues. - Performed normal CSRF submits. - Added writes to an un-CSRF'd page, got an exception. - Executed conduit methods. - Did login/logout (this works because the logged-out user validates the logged-out csrf "token"). - Did OAuth login. - Did OAuth registration.
