+
+Follow this checklist to help us incorporate your contribution quickly and easily:
+
+* [ ] Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
+* [ ] Format the pull request title like `[ISSUE #123] Fix UnknownException when host config not exist`. Each commit in the pull request should have a meaningful subject line and body.
+* [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
+* [ ] Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in [test module](https://github.com/alibaba/nacos/tree/master/test).
+* [ ] Run `mvn -B clean package apache-rat:check findbugs:findbugs -Dmaven.test.skip=true` to make sure basic checks pass. Run `mvn clean install -DskipITs` to make sure unit-test pass. Run `mvn clean test-compile failsafe:integration-test`  to make sure integration-test pass.

+##### 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
+```
