Another WordPress plugin patched 7 security bugs over 2 releases, and WordPress core had a vulnerability disclosed publicly before they could release a patch.

With so much news to cover about vulnerabilities, it was a good week to discuss vulnerability severity and how all vulnerabilities are not equal.

Episode 4

This week marks the final week of 2021, and with the year coming to a close it is a great time to reflect on the past, present, and future. So that is the format of this week's update.

Starting with the past, Robert takes time at the end of each year to think about all that has changed in his life since the last year. He recommends you try this as well, it only takes a few minutes and the only recommendation he has is to start with the positive.

Think back to successful projects that have come to completion, new skills learned, perhaps recall any pivots that you made to change the direction of your life or company, and goals you reached. You're allowed to surprise yourself with what you have accomplished.

Feel free to pause now and take a minute to reflect on at least one good thing from 2021.

But that is enough of the past, let's move on to the news of the present! I hope you thought of something positive because this week's vulnerability news is for a critical plugin vulnerability in a WordPress plugin with, get this: an unauthenticated arbitrary option table update vulnerability in it.

It looks like the vulnerabilities of the past few weeks just keep on repeating themselves, so let's get to the vulnerability news.

Episode 3

This week's news may sound like deja-vu, as he covers more of the same topics as last week. Log4j is still a leading security concern, and the project's developers have released yet another security update, this time to address a Denial of Service concern.

He also once again discusses WordPress plugins with options table update vulnerabilities reported in them ... the difference this time is, there is no patch.

In this week's knowledge share, Robert compares the log4j project's quick security response, to that "not to be named for your protection" WordPress plugin that has an options update insecurity that has not yet been properly patched.

This, lack of response, is an unfortunate reality security researchers sometimes face. I will share with you the inside knowledge on what happens when WordPress plugin or theme developers choose to ignore security reports.

Episode 2

It is mid-December, and we are still waiting to see the total impact of a vulnerability reported in the open-source component: log4j. This is a library used in a large number of java applications and you will get the details later during this week's knowledge share.

In WordPress security news this week, there are a few plugins that have serious vulnerabilities reported in them, including unauthenticated attacks that may affect tens of thousands of websites. So, let's get to that right away….
