I am so happy that I asked Codex to rewrite our website as Hugo templates which allowed us to statically host it and get rid of Wordpress. So much stress gone!
For the Wordpress RCE (nominally CVSS 9.2), it looks like many standard deployments of WordPress would be affected, barring extra mitigations. But in the case of these Hugo ones (9.3), it looks like very specific circumstances (anti-mitigations, if you will) are needed. E.g. running arbitrary builds of untrusted user content without a sandbox; running it in a GitHub workflow against PRs from untrusted contributors, etc.
Never had to worry again about sequencing updates where the update changed the database schema and I had a cluster of 6 web servers. Never had to worry anymore about long ass load times because the web servers were in 3 colos and wordpress wouldn't play nice with local read only mysql replicas. No more worries about why pingbacks and comments keep showing up in the database even those those features were turned off; at least they weren't showing up in a moderation queue, but still.
My website is hosted on 1and1 via PHP. I am guessing that this would not work for me as installation needs server access. Moving to VPS, along with transferring domain, would require more time than I would like to spend. Thanks.
