This change downgrades Newtonsoft.Json from version 13.0.1 to 12.0.2. Downgrading package versions can introduce known security vulnerabilities and bugs that were fixed in later versions. Version 13.0.1 (released in 2021) includes important security fixes and improvements over 12.0.2 (released in 2019). Unless there's a specific compatibility requirement, it's recommended to keep the newer version or upgrade to the latest stable version.

Both Newtonsoft.Json (line 5) and System.Text.Json (line 6) namespaces are imported, but only Newtonsoft.Json is used in the code (line 136). Importing both JSON libraries can cause confusion about which serialization approach is being used. Consider removing the unused System.Text.Json import, or if this is intentional for demo purposes, add a comment explaining why both are imported.

The comment "VULNERABILITY: Vulnerable regex pattern susceptible to ReDoS" contains redundancy with both "VULNERABILITY" and "Vulnerable" used together. Consider simplifying to "VULNERABILITY: Regex pattern susceptible to ReDoS" for better readability.

This assignment to deserializedObject is useless, since its value is never read.

| JsonConvert.DeserializeObject(jsonInput, settings); |
