Welcome back to the Patchstack Weekly security update! This update is for week 51 of 2021.

This week's news may sound like deja-vu, as I will cover more of the same topics as I did 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.

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