/**
 * Secure replacement for java.net.URL.
 *

 * This class should be used instead of java.net.URL.
 *

 * This class does some control access and manages access-tokens via URL. If a
 * URL contains a access-token, similar to a user prefix, SURL loads the
 * authorization config for this user-token and passes the credentials to the
 * host.
 *

 * Example:

 *
 *

 *     SURL url = SURL.create ("https://jenkins-access@jenkins.mycompany.com/api/json")
 *

 *
 * The {@code jenkins-access} will checked against the Security context access
 * token configuration. If a configuration exists for this token name, the token
 * will be removed from the URL and the credentials will be added to the
 * headers. If the token is not found, the URL remains as it is and no separate
 * authentication will be performed.
 *

 * TODO: Some methods should be moved to a HttpClient implementation, because
 * SURL is not the valid class to manage it.

 * TODO: BAD_HOSTS implementation should be reviewed and moved to HttpClient
 * implementation with a circuit-breaker.

 * TODO: Token expiration with refresh should be implemented in future.

Output:
【漏洞类型】安全配置绕过漏洞
【严重性】High
【漏洞摘要】`OptionFlags.ALLOW_INCLUDE`标志的使用导致了潜在的安全风险。在`OptionFlags`类中，`ALLOW_INCLUDE`标志被用于控制文件和URL的导入是否允许。然而，这个标志在多个地方被硬编码为`true`，没有根据当前的安全配置进行动态调整，使得即使在更严格的`SecurityProfile`模式下（如`SANDBOX`或`INTERNET`），PlantUML仍然允许文件和URL的导入。这可能导致路径遍历、文件读取和网络请求的安全问题。
【关键代码模式】硬编码的安全标志、未根据安全配置动态调整的标志、`ALLOW_INCLUDE`标志的使用。
【修复方法说明】通过移除硬编码的`ALLOW_INCLUDE`标志并根据`SecurityProfile`的设置动态控制导入，修复了安全配置绕过的问题。

Output:
【漏洞类型】弱密码策略漏洞
【严重性】Medium
【漏洞摘要】修复后的代码增加了对新旧密码相同的校验以及密码复杂度的校验。在原始代码中，用户可以将旧密码和新密码设置为相同，这可能导致密码被轻松猜测或重置。此外，原始代码没有对新密码的复杂度进行任何限制，用户可以设置非常简单的密码，这降低了系统的安全性。
【关键代码模式】与漏洞相关的代码模式包括：`StringUtils.equals(request.getOldPassword(), request.getNewPassword())` 以及 `request.getNewPassword().matches("^(?!.*\\s)(?=.*[A-Z])(?=.*[a-z])(?=.*[0-9])(?=.*[\\W_]).{8,30}$")`。
【修复方法说明】修复方法通过添加新旧密码相同的校验以及对新密码的复杂度校验来解决问题，确保用户密码的安全性。
（最佳实践：使用强密码策略，确保密码包含大小写字母、数字和特殊字符，并且新密码与旧密码不同。）
