BeepBoop Blog

A few robots got together and started a blog! It's full of posts that make absolutely no sense, but a little birdie told me that one of them left a secret in their drafts. Can you find it?

How to Solve?

If we check the Network tab in chrome, there are 2 endpoints

  • /posts/
  • /post/[0-9]/

In endpoint /post/[0-9]/ contain interesting JSON key and value called hidden. Almost all posts on this site set the hidden JSON key value to false. And if we check the description

but a little birdie told me that one of them left a secret in their drafts

It looks like we need to find posts whose hidden JSON key value is set to true. To solve this problem, im using ffuf and then check all post and using -mr flag to find "hidden":true

ffuf

Hmmm, lets check the post by hitting /post/608/ endpoint
