Output:
【漏洞类型】反序列化漏洞
【严重性】High
【漏洞摘要】该代码中存在反序列化漏洞，主要体现在`ParserConfig.checkAutoType`方法中。该方法允许通过传入的`typeName`参数来动态加载类，并通过`TypeUtils.loadClass`方法实例化。如果攻击者可以控制`typeName`，则可以利用此功能加载任意类，包括恶意类，从而可能导致代码执行、数据泄露或其他安全问题。
【关键代码模式】`checkAutoType`方法中涉及的关键代码模式包括：
- `TypeUtils.loadClass(typeName, defaultClassLoader, true);`：允许动态加载类。
- `Arrays.binarySearch`：用于检查允许或禁止的类列表。
- `String className = typeName.replace('$', '.');`：处理类名中的特殊字符。
【修复方法说明】修复方法通过在`checkAutoType`方法中添加新的条件，防止加载以`Exception`结尾的类，并在加载类之前增加对`expectClass`的检查，确保加载的类是预期的子类。同时，增加了对`Throwable`类的检查，避免在非开启`autoTypeSupport`的情况下加载异常类。这些措施有助于限制动态类加载的范围，减少潜在的安全风险。

【漏洞类型】安全漏洞
【严重性】Low
【漏洞摘要】此代码中存在安全漏洞，主要体现在版本更新不及时的问题上。在`publiccms-parent/build.gradle`、`publiccms-parent/pom.xml`和`publiccms-parent/publiccms-core/src/main/java/com/publiccms/common/constants/CmsVersion.java`文件中，项目的版本号没有更新，仍然使用的是过时的`V4.0.202204.a`版本。虽然这不是一个典型的路径遍历漏洞或未验证用户输入的问题，但版本过时可能导致项目中存在已知的安全漏洞未被修复。
【关键代码模式】版本号定义和使用
【修复方法说明】更新版本号为`V4.0.202204.b`，并确保所有依赖库都使用最新的稳定版本。同时，建议定期检查和更新项目依赖库以修复已知的安全漏洞。
