I've heard people mention curl and imagemagick. Any others that you know about?

Log4j was a fun one to watch unfold everywhere when things went haywire

    The neat thing about the log4j thing was even a cursory explanation of the vulnerability made anyone with a passing familiarity with security say, "Why the fuck would that even be a feature?!"

    Basically it involved parsing JNDI stuff which involved grabbing remote code (but that was a niche feature of JNDI in the Dev's defense). Basically, you may think it is just something like variable substitution but can involve much crazier stuff

    That was not a fun week to be a developer.

    As a non-java company developer at the time, I think our biggest challenge was explaining to everyone that Log4j didn't affect us. It took a non-zero amount of effort because a lot of customers panicked. To be fair, it was also an industry where confidentiality is important.

    Oh man. I missed it by like a month. I graduated with my bachelors in December, and started in January. I was hearing horror stories from my new coworkers about how people had to cancel vacations to get stuff patched asap

    It was if none of your code used log4j. I remember being very grateful that I had chosen java.util.logging and Logback for my Java logging needs.

    That one was so annoying because you had to be using the log server to have any issues. If your network was locked down, the log server was disabled, or if you happened to be using a version that was from before the log server was added, then there were no issues. But clients just heard "log4j" and thought it was unsafe.
