Hello,

At first thank a lot for you work for this project he is very nice. I found that some field in the log from coraza are duplicated see the log bellow when i tested an SQL injection.

{"level":"error","ts":1668631193.1862295,"logger":"http.handlers.waf","msg":"[client \"192.168.1.1\"] Coraza: Warning. SQL Injection Attack: SQL Boolean-based attack detected [file \"/ruleset/coreruleset/rules/REQUEST-942-APPLICATION-ATTACK-SQLI.conf\"] [line \"0\"] [id \"942130\"] [rev \"\"] [msg \"SQL Injection Attack: SQL Boolean-based attack detected\"] [data \"Matched Data:  1=1 found within ARGS:q: '1 OR 1=1\\\"\"] [severity \"critical\"] [ver \"OWASP_CRS/4.0.0-rc1\"] [maturity \"0\"] [accuracy \"0\"] [tag \"application-multi\"] [tag \"language-multi\"] [tag \"platform-multi\"] [tag \"attack-sqli\"] [tag \"OWASP_CRS\"] [tag \"capec/1000/152/248/66\"] [tag \"PCI/6.5.2\"] [tag \"paranoia-level/2\"] [hostname \"\"] [uri \"/?q=%271%20OR%201=1%22\"] [unique_id \"VLS1AeezUlAFnWQyFd2\"]\n[client \"192.168.1.1\"] Coraza: Warning.

if you beautify it:

{"level":"error","ts":1668631193.1862295,"logger":"http.handlers.waf","msg":"[client \"192.168.1.1\"] Coraza: Warning. SQL Injection Attack: SQL Boolean-based attack detected [file \"/ruleset/coreruleset/rules/REQUEST-942-APPLICATION-ATTACK-SQLI.conf\"]

[hostname \"\"]
[uri \"/?q=%271%20OR%201=1%22\"]
[unique_id \"VLS1AeezUlAFnWQyFd2\"]\n"}

We can see that there is duplication, is it me or ?
