Is moodle secure? [closed]

On the one hand, a lot of schools and universities use Moodle and especially during the containment. On the other hand, moodle store a lot of personal data such as pictures, name, emails addresses, sometimes phones number or physical address.

I feel like moodle has a reputation for being pretty insecure, my rumors never get past the hypothetical stage. What’s really going on ? Is Moodle generally well secured or is it a real sieve ?
