@davidgerard According to this page:

https://thephp.foundation/blog/2026/10/21/todays-php-security-release-and-how-were-strengthening-php-security/

they were informed of one of the vulnerabilities in 2024, and wasted much of the intervening time arguing about how to fix it. So I'm not sure this one qualifies as "quick fix".

(Still glad to not be running any PHP on anything I manage...)
