Welcome back to the Patchstack Weekly security update! This update is for week 11 of 2022. This week is all about plugin vulnerabilities and the State of WordPress Security 2021 whitepaper.

There is some big news this week, but really I should say last week. Patchstack released our State of WordPress Security Whitepaper for 2021 on March 9th or last Wednesday.

I will be giving a short summary of some high points in this week's knowledge share, but if you would like to read the whole thing you can view it on patchstack.com for free, no email or registration is required.

Before I talk about WordPress security from 2021 … I need to tell you about this week's vulnerability news, which includes a WordPress core security release (5.9.2) and five WordPress plugins that patched high-risk security bugs in them in the last week. Emphasis on high risk too, they require no authentication for an attack to be successful.
