Why are people looking for vulnerabilities?
Why are there security flaws in software?
There are many reasons why a flaw can appear in a plugin or a theme. It can be due to simple mistakes, misleading documentation, lack of experience working with WordPress code, or a ton of other reasons. Many plugins also use 3rd party libraries for different tasks, and it could be here that a security flaw exists.
Many times this problem can be alleviated by keeping your plugins up to date. Still, there are also cases where a vulnerability is made public even before the developers have a chance to know about it and create a fix.
