Hi @carloshssouza, in fact those links should point to:

• https://owasp.org/API-Security/editions/2019/en/0xa3-excessive-data-exposure/
• https://owasp.org/API-Security/editions/2019/en/0xa6-mass-assignment/
• https://owasp.org/API-Security/editions/2019/en/0xa4-lack-of-resources-and-rate-limiting/

Would you mind fixing that on you side so that I can accept the PR?

Cheers, Paulo A. Silva
