Today's update includes a fix for a vulnerability that allowed hackers to create a jailbreak for the iOS 12.4 update, according to Apple's security support document. Apple actually addressed the vulnerability in iOS 12.3, but then accidentally unpatched it in the iOS 12.4 update.

Available for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generation

Impact: A malicious application may be able to execute arbitrary code with system privileges

Description: A use after free issue was addressed with improved memory management.

CVE-2019-8605: Ned Williamson working with Google Project Zero

After hackers discovered that the vulnerability was once again available, it didn't take long for a jailbreak to be created. The security issue also left iOS devices vulnerable to hacking attempts, which is why Apple likely worked quickly to correct it.

According to Apple's release notes, the update includes "important security and stability updates" and is recommended for all users.

In all seriousness, who is jailbreaking anymore anyway? The features we want are basically already on the OS, and really doesn't have any relevant benefits anymore other than extreme customization. At least, thats my opinion on it.

Or, just like anything else in life, they are probably doing it just to say they can do it.

It's not only about jailbreaking. This is an exploit that could allow any app in the App Store to jailbreak your device and allow the app to go rogue.

In all seriousness, there's a post like this in EVERY jailbreaking related thread. Know what the capabilities are before you act like it's beneath you. Comedic response.

I used to think that as well, I have not jailbroken since iOS 11, but I recently saw a video of all the features and tweaks in the last jailbreak and it is AMAZING. Apple should learn from these guys, something I hate about the company is their arrogance and slowness to give users what they want.

About your phrase "they are probably doing it just to say they can do it", I disagree, jailbreaking is quite easy today, nothing to brag about, do you remember how we did it back in iOS 5, iOS 6??? That was a process.
I can remember the days of jailbreaking iOS 2, 3, and 4.x. Now THOSE were some lengthy tutorials lol. Redmond Pie's guides used to involve like a dozen steps at least, and if you screwed up just one of them it could've meant an unsuccessful jailbreak or at worst, a bricked device. But those were the Steve Jobs days when Apple was much more "the customer doesn't know what they want until we tell them they want it" oriented, and so it was much more liberating to break out of their lockdown than I feel like it would be today.
