From the Mongo docs-

By default, the update() method updates a single document that matches its selection criteria. Call the method with the multi option set to true to update multiple documents.

So you should run your query like this:

db.posts.update(
  {author:{$lt:0}},
  {$set:{author:582127753}},
  { multi: true }
)
