Open source that site. Vet a few devs to have access to the source to begin with then opensource it. Or even better, let the community rewrite the source from scratch. How hard can it be? and there are often a lot of people willing to contribute to open-source projects.

"How hard can it be?" <--- yeah, that's how you end up with vulnerable sites.

Not if you make security your number one goal from the beginning. But "letting the community rewrite the site" would be very complicated, especially on a niche website such as Project Euler, where a lot of its users are opinionated and would probably take a long time to reach consensus on anything.

If security were really your "number one goal", then you would not create a site at all.

Number two after availability, then.
