## What is CVE-2022-36072?

CVE-2022-36072 is a medium-severity authentication bypass vulnerability in mesosoi silverwaregames-io-issue-tracker, published on 6 Sep 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

SilverwareGames.io is a social network for users to play video games online. In version 1.1.8 and prior, due to an unobvious feature of PHP, hashes generated by built-in functions and starting with the `0e` symbols were being handled as zero multiplied with the `e` number. Therefore, the hash value was equal to 0. The maintainers fixed this in version 1.1.9 by using `===` instead of `==` in comparisons where it is possible (e.g. on sign in/sign up handlers).

Weakness: CWE-597 (Use of Wrong Operator in String Comparison)
