WordPress Coding Standard 2.0 removed the sniff
WordPress.Security.NonceVerification.NoNonceVerification:
```
The WordPress.Security.NonceVerification sniff used the same error code for both an error as well as a warning.
The old error code NoNonceVerification is no longer used.
The error now uses the Missing error code, while the warning now uses the Recommended error code.
```
(from
d45f5e5cf3/CHANGELOG.md (200-rc1---2018-12-31))
This commit updates WooCommerce code and replaces all instances where WordPress.Security.NonceVerification.NoNonceVerification verification was used with either WordPress.Security.NonceVerification.Missing or
WordPress.Security.NonceVerification.Recommended. In a few cases WordPress.Security.NonceVerification.NoNonceVerification was used but was not needed, so instead of replacing the sniff, the line was removed. In two other cases, I removed other unrelated sniffs that were not needed.
