WordPress Theme Vulnerabilities

Selio – Real Estate Directory
Another Themeforest theme with no installation numbers. The vulnerability was in version 1.1 and lower but with a fix released in version 1.1.1.
WordPress Core Vulnerabilities
WordPress core was on a winning streak for no vulnerabilities since March. The streak is over with several vulnerabilities in the latest version of WordPress and one that goes back to 5.2.2 and to prior version too.
This isn’t a bad thing, though. It means WordPress has a lot of eyes on it so even the smallest vulnerability will get found eventually. That’s the beauty with open source. If there’s an issue, someone will find it because everyeone can see the code.
Proprietary software is exactly the opposite. If someone finds a vulnerability there’s a good chance they’re malicious. The only one who can find it and fix it is a small group who have access to the code.
Enough of that, now it’s time to cover some of the issues found in a recent version of WordPress core.
Up to and including WordPress 5.2.2
The following linked vulnerability is in WordPress version 5.2.2 and all prior versions of WordPress. That means no matter what version you’re on, make sure you update to either the most recent version or a version in your line of installation with the fix.
For example, if you’re using 4.8.5 then update to version 4.8.10 if that has the fix. This is a theoretical example, though, and you should consult all the WordPress versions and fixed if you’re using anything but the most recent version.
There were several vulnerabilities discovered in version 5.2.2 which makes it essential that you update as soon as possible to version 5.2.3 or newer.
These links go over all the vulnerabilities discovered and in what version they were patched.
That’s it for this month! WordPress lost its long-running record for no vulnerabilities but they were patched quick. That’s why WordPress is one of the most secure platforms on the internet.
Even though WordPress is extremely secure on its own, updates and maintenance are essential which is why it’s important to continue using a reputable WordPress maintenance service.
