Exploit: Submit an easy problem that you've solved already

[aryanpingle]

A few problems with the current system:

• The extension doesn't care what problem you solve, as long as you submit something successfully. That means I can navigate to an easy problem and submit the solution.
• Even worse, it doesn't check if you've solved the given problem already. In that case you can just resubmit the solution saved by LC and you're done.

Potential Solutions

• Make sure the submission-checker takes into account the problem statement
• Use the publicly available, free-to-use LeetCode API's to go through all of the user's submissions and make sure your random problem isn't in those already. We can easily assume the list of the user's solved problems is <= 1,000,000 XD

haha yeah that's one of the big exploits. My plan so far is this:

1. For the first issue, Simply do a check if the user's current leetcode url that they're on equals the assigned problem url, and if it is then it should activate, if it's anything else it won't count.
2. For the second issue try to delete the already saved submission, and lock their submission tab (probably through the content files) If anyone has better ideas or wants to do this themselves feel free

I'll try to code up a solution for the first one, and try to put a link here that lets you get a JSON of the user's solved problems.

BTW, love the idea for this extension, hope it becomes a big thing :)

sweet thanks so much I appreciate it a lot. It'd be funny if this extension actually got popular. Another idea to prevent resubmission (idea just came to my mind): Could add a timer where if they make a submission in less than 1-5 minutes after being redirected (mess around with this timer), the problem shouldn't count since I doubt they solved a leetcode problem that fast. Could also show a funny message saying "Wow you really used an old submission, you monster" something along the lines
