Under "Security > Site health" you're displaying "Your PHP version is outdated".
When doing so, it would be useful if you included which version you're seeing here.
Anyhow it doesn't make any sense displaying this for sites who is running on t.ex. PHP 8.2.29, as PHP 8.2 is still fully supported regarding security until December 31, 2026 (https://www.php.net/supported-versions).
There is absolutely no reason to warn about PHP 8.2 at this stage, it's secure, and should not be flagged as outdated and a security issue. That's completely wrong in so many ways.
You can indeed recommend people to use PHP 8.3, as also WP does, but it's not outdated in any way.
WP Site Health now lists it as a
recommended
improvement, with the title text:
"Your site is running on an
older
version of PHP (8.2.x), which should be updated"
Later when it's being considered EOL, they will change it to
critical
, and then also switch the title text into:
"Your site is running on an
outdated
version of PHP (8.2.x), which should be updated."
It's a huge different in those, and what you're currently doing, flagging it as outdated and a security risk in red ... ;)
