What an attacker can do
The same Coraza variable An unauthenticated attacker can place a malicious value in a nested property and then overwrite only Coraza's representation with a harmless dotted property: ```json { "account": { "role": "1' OR '1'='1" }, "account.role": "safe" } ``` Coraza stores both properties as `ARGS_POST:json.account.role`; the later value `safe` replaces the SQL-injection value. Source advisory’s CVSS 3.1 assessment rates confidentiality and availability impact as none; integrity impact as low.
