+##### 4.1.2.1.1. Type Conversion during YAML Parsing
 
+By default, starting from version 1.1.2, this library uses `SafeConstructor` for type conversion during YAML parsing. This is done to ensure that potentially unsafe code is not executed during the parsing process. `SafeConstructor` provides a secure construction logic for mapping YAML structures to Java objects.
 
+**System Property Toggle**
+
+To maintain compatibility with versions prior to 1.1.2, we have introduced a system property toggle named `yamlAllowComplexObject`. Prior to version 1.1.2, the library defaulted to using `Constructor`, another constructor in the SnakeYAML library that supports more complex object mapping. Starting from version 1.1.2, the default is switched to `SafeConstructor`.
+
+**Potential Risks**
+
+It's important to note that enabling `Constructor` introduces some potential risks, particularly the risk of Remote Code Execution (`RCE`). This is because `Constructor` allows more flexible object construction, but it also increases the risk of handling malicious YAML input.
+
+**Recommendations**
+
+- We recommend using the `NacosConfigConverter` for custom conversions.
+
+**If You Must Use `Constructor`**
+
+- Ensure that the source of the YAML data is secure.
+
+**How to Disable `SafeConstructor`**
+
+You can set the toggle by adding a JVM system property when starting your application. For example, in the command line:
+
+```bash
+java -DyamlAllowComplexObject=true -jar your-application.jar
+```
