You may be aware that OWASP 2017 was recently updated to OWASP 2021.

The biggest changes involved updates to the original OWASP Top 10.

• There are now three new categories; four categories with naming and scoping changes; and some consolidation in the Top 10 for 2021.

• This link, https://owasp.org/www-project-top-ten/, will provide a detailed explanation of these changes.
