MongoDB Server

Affected releases:

Info

A normal user who has write access to the "local" database is currently not disallowed from writing arbitrary data to the oplog. We should discuss more stringent rules about when (if ever) to allow these kinds of arbitrary oplog writes.

In the past being able to write to the oplog has been useful for support, and we don't want to completely remove that ability. Restricting access to the oplog collection with a builtin role doesn't require any major changes to the auth subsystem, and we can think about doing that, but if a user has been given write access to the oplog collection then we've decided they should be able to write to it. greg.mckeon commented on Tue, 24 Jul 2018 17:13:50 +0000: spencer.jackson if you're picking this up, would it be significant extra work to pick up SERVER-29826 as well? spencer.jackson@10gen.com commented on Thu, 4 May 2017 20:18:41 +0000: I thought about this and asked around. This seems like a reasonable request.
