Output:
【漏洞类型】输出未正确转义漏洞
【严重性】Medium
【漏洞摘要】原始代码中存在多个输出未正确转义的问题，特别是在将用户输入或动态生成的内容直接嵌入到HTML中时。例如，在 `_material_revisions_jstemplate.ftl` 文件中，用户显示名（`modification.getUserDisplayName()`）和评论（`modification.getComment()`）未经过HTML转义。这可能导致跨站脚本攻击（XSS），因为恶意用户可以通过注入恶意脚本来操纵页面内容或窃取用户信息。

【关键代码模式】
- 未使用 `?html` 或 `?js_string` 等FreeMarker内置的转义功能输出用户生成的内容。
- 未验证用户输入的合法性。

【修复方法说明】
修复方法通过在FreeMarker模板中使用 `?html` 和 `?js_string` 等转义功能来确保用户生成的内容在输出到HTML或JavaScript时被正确转义。此外，修改了Freemarker配置，设置 `recognizeStandardFileExtensions` 为 `true`，并更改了模板文件的扩展名从 `.ftl` 到 `.ftlh`，以强制使用HTML自动转义功能。

Output:
【漏洞类型】SQL注入漏洞
【严重性】High
【漏洞摘要】原始代码中，`MySQLSinkDTO`类的`getFromRequest`和`getFromJson`方法接收并处理用户输入的JDBC URL和属性。尤其是在`getFromRequest`方法中，`jdbcUrl`参数被直接传递给了`MySQLSinkDTO`的构造器，而没有进行任何过滤或验证。这意味着攻击者可以构造恶意的JDBC URL，其中包含SQL注入攻击代码，这些代码将在应用程序连接数据库时被执行。严重性等级为High，因为这可能导致数据泄露、数据篡改或系统控制权的丧失。
【关键代码模式】
1. `getFromRequest`方法接收`MySQLSinkRequest`并直接使用其`getJdbcUrl`方法返回的值。
2. `getFromJson`方法直接解析`extParams`字符串，没有对其中的参数进行验证或过滤。
3. `filterSensitive`方法用于过滤敏感参数，如`autoDeserialize`、`allowLoadLocalInfile`等。
【修复方法说明】修复方法通过将`MySQLDataNodeDTO`类的`convertToJdbcurl`方法中的`jdbcUrl`参数传递给`MySQLSinkDTO`类的`filterSensitive`方法，确保JDBC URL在转换之前被过滤掉潜在的敏感参数。这解决了直接使用用户输入的JDBC URL可能引发的SQL注入漏洞。修复方法遵循了输入验证的最佳实践，确保所有用户输入都经过适当的验证和过滤。

Output:
【漏洞类型】正则表达式长度限制漏洞
【严重性】Low
【漏洞摘要】在`OperatorMatches`类中，`matches`操作符的第二个操作数（正则表达式）没有长度限制，这可能导致性能问题或意外行为。具体表现为`getValueInternal`方法中没有对正则表达式长度进行验证。
【关键代码模式】`Pattern.compile(rightString)`, `getValueInternal`方法
【修复方法说明】修复方法通过添加`checkRegexLength`方法来限制正则表达式的最大长度，从而提高代码的健壮性和可预测性。
