Output:
【漏洞类型】Token刷新漏洞
【严重性】High
【漏洞摘要】Token刷新功能存在安全漏洞，可能导致未授权的访问。在JWTServiceImpl类中，refreshToken方法允许用户通过提供旧的JWT令牌和新的过期时间来刷新令牌，而没有验证旧令牌的权限或角色。这使得攻击者可以利用已过期的令牌来获取新的令牌，从而绕过身份验证机制。
【关键代码模式】refreshToken方法、JwtService接口、未验证的旧令牌和角色。
【修复方法说明】移除refreshToken功能，防止用户通过已过期令牌获取新的令牌。

CHANGELOG.md
### 代码内容：
# Changelog
All notable changes to this project from version 5.0.0 upwards are documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

## [5.2.1] – Unreleased

### Added
- Possibility to reorder table columns in the tables section upstairs.

### Changed
- Render internal links in text pages with no target attribute (that the Quill editor adds by default).
- The welcome page is now a standard text page.
- Security.groovy can now have user beans injected with @Autowired.

### Fixed
- Backwards compatibility: revert `T extends Serializable` in CRUD actions, introduced in v5.2.0. [#428](https://github.com/ManyDesigns/Portofino/issues/428)
- Authentication token refresh after expiration. [#430](https://github.com/ManyDesigns/Portofino/issues/430)

## [5.2.0] – 2020-11-30

### Added

- User interface extensibility improvements:
  - Custom pages in HTML and JavaScript with no Angular knowledge required (example in demo-tt)
  - All pages can load custom JavaScript (example in demo-tt)
  - Page templates can include several sections where child pages can be embedded (like Portofino 4)
  - demo-tt profile page (example of custom component)
  - Progressive Web Application (PWA) using angular-pwa, example in demo-tt
- Full support for POJO-based persistence:
  - Export generated classes to actions and shared code
  - Export generated classes to the file system so that your IDE can pick them up
  - Allow to configure the entity mode of each database mapping from the UI (the default is still map-based)
- Authentication improvements:
  - Better support for external auth (e.g., in a microservices setting). Built-in support for authentication
    against KeyCloak.
  - application/json login endpoint (in addition to the existing form-based endpoint).
  - Better handling of token expiration in the client.
- Per-database Hibernate properties.
- Support annotations on databases.
- Quartz jobs now run with a working Shiro environment.
- Ability for extensions and user code to "mount" actions to arbitrary mount points in the action tree.

### Changed
- Angular updated to version 11
- Groovy updated to version 3
- Various other dependencies updated for security & bug fixes
- CRUD REST API versioning with X-Portofino-API-Version header
- CRUD REST API changes (legacy behavior is still the default):
  - Bulk update (PUT) optionally returns list of modified IDs
  - Bulk delete (DELETE) optionally returns list of deleted IDs
- Generated Security.groovy is now based on annotations on the model rather than hard-coded values

### Removed
- Maven profile "portofino-development" which has been superseded by Docker
- Maven profile "no-frontend-build" (use -P-build-frontend)
- `PortofinoRoot.mount` method and related methods, replaced by `ActionLogic.mount`. This is a breaking API change for
  extensions making use of the removed methods, but none are known to us (also because the methods are undocumented and
  only used internally by portofino-upstairs).

### Fixed

- Newly created CRUD pages don't have create/update buttons ([#406](https://github.com/ManyDesigns/Portofino/issues/406))
- Page configuration is broken for pages using the default template implicitly ([#423](https://github.com/ManyDesigns/Portofino/issues/423)).
- User self-registration is broken in several ways ([#414](https://github.com/ManyDesigns/Portofino/issues/414)).
  Note that **this involves a breaking API change** in `Security.groovy`, specifically, the signature of the method
  `saveSelfRegisteredUser` has changed to return both the token and the email of the newly saved user.
  However, typical `Security.groovy` files (generated by the wizard) don't override that method, so most users shouldn't
  have to do anything.

## [5.1.4] – 2020-07-04

### Added
- "Fat jar" deployment option (with embedded Tomcat)
- Restored the profile section of demo-tt with an example custom Angular component
- Included the MariaDB JDBC driver in the binary distribution

### Changed
- Improved wizard and UI
- Postgres driver version updated
- Include explicit 'tt' schema in SQL queries in demo-tt (plays nicer with Postgres)
- Mail module as a separate artifact

### Fixed
- CRUD pages generated by wizard don't have buttons ([#372](https://github.com/ManyDesigns/Portofino/issues/372))
- Broken blob download URL and code ([#384](https://github.com/ManyDesigns/Portofino/issues/384))
- Pressing the Enter key on a search field does not perform a search ([#383](https://github.com/ManyDesigns/Portofino/issues/383))

## [5.1.3] – 2020-05-17

### Added
- Notifications bell showing up to 20 messages
- More error reporting in the wizard
- Spanish translation of the UI, thanks to Gabriel Mautino
- Possibility for buttons to prevent double submit by returning an Observable
- RestEasy support (alternative to Jersey JAX-RS)
- Tested on WildFly 19.0.0.Final

- Arrays in XML annotations ([#325](https://github.com/ManyDesigns/Portofino/issues/325))
- Local API with IPv6 addresses ([#327](https://github.com/ManyDesigns/Portofino/issues/327))
- Can't save selection providers ([#328](https://github.com/ManyDesigns/Portofino/issues/328))
- Generated `Security.groovy` errors when loading groups ([#329](https://github.com/ManyDesigns/Portofino/issues/329))
- OPTIONS with expired JWT fails triggering bad CORS ([#333](https://github.com/ManyDesigns/Portofino/issues/333))
- Server-side localized info/warning/error messages ([#334](https://github.com/ManyDesigns/Portofino/issues/334))

## [5.1.1] - 2020-01-10

### Added
- Text pages (client only, no I18n).
- Support deployment behind a proxy.
- Documentation of Docker development, debugging and deployment in the archetype.
- Example deployment of demo-tt as Docker containers on Amazon ECS.

- Several wizard improvements and fixes.

### Fixed
- Model not properly saved ([#294](https://github.com/ManyDesigns/Portofino/issues/294), [#303](https://github.com/ManyDesigns/Portofino/issues/303)).
- Page configuration not properly saved ([#310](https://github.com/ManyDesigns/Portofino/issues/310), [#311](https://github.com/ManyDesigns/Portofino/issues/311)).
- Names of mapped database objects not escaped ([#297](https://github.com/ManyDesigns/Portofino/issues/297)).
- New actions added with bad class names ([#301](https://github.com/ManyDesigns/Portofino/issues/301)).
- Database synchronization issues with MariaDB and PostgreSQL ([#283](https://github.com/ManyDesigns/Portofino/issues/283), [#298](https://github.com/ManyDesigns/Portofino/issues/298)).
- KeyManager with no password (ported from Portofino 4).

## [5.1.0] - 2019-10-31

### Added
- Map database views, by default as read-only, but overridable.
- Support non insertable and/or non updatable entities in CRUD actions.
- Annotations are propagated from model to annotated classes.
- Support persistent Java 8+ Date and time API values.
- Generic database platform for unrecognized databases.
- Support for development and debug with Docker, both in demo-tt and in the archetype.
- Periodically retry database connections that have failed at startup if Quartz is available.
- Filter CRUD fields according to permissions (at the level of the ClassAccessor).
- Filter configuration fields according to permissions.
  In particular, the CRUD query is hidden if the user is not a developer.
- Proper support for `@DatabaseBlob` upstairs.

### Changed
- **Update Hibernate to the 5.x branch**, in particular to version 5.4.7.Final.
    The Hibernate Session factory is now configured with annotated Java classes generated at runtime.
    The ad-hoc code for Hibernate 4 has been removed.
- Deprecate the single `portofino-model.xml` file in favor of multiple `portofino-model/<database-name>/database.xml` files.
  Legacy files are supported and converted to the new format upon save.
- Change the format of annotations in the model and in `configuration.xml`.
  Annotations in the legacy format are converted upon save.
- Replace `java.io.File` with Apache Commons VFS `FileObject` in `Persistence`.
  **This is a breaking API change.**
- Update all uses of Commons Configuration to version 2.6, including Commons Configuration 1.x uses.
  **This is a breaking API change.**
- Ensure that Portofino 5 can run without a Java compiler (JDK) available.

### Fixed
- Virtual properties not saved properly [[#269]](https://github.com/ManyDesigns/Portofino/issues/269).
- Wizard failing on connections to Oracle databases [[#271]](https://github.com/ManyDesigns/Portofino/issues/271).
- Minor upstairs, Spring and Security.groovy fixes.

## [5.0.3] - 2019-09-25

### Added
- Support for MariaDB Connector/J.
- Simple automatic JWT renewal (this means that user sessions do not expire during regular user activity).
- Possibility to override buttons in subclasses [[#253]](https://github.com/ManyDesigns/Portofino/issues/253).

### Changed
- JWT expiration property is now called `jwt.expiration`.
- Better Spring context reloading and more rational context layout w/ documentation. Still doesn't support all scenarios.
- Ensure Portofino does not create any HTTP sessions by itself in any circumstances [[#255]](https://github.com/ManyDesigns/Portofino/issues/255).

### Fixed
- Badly broken `Security.groovy`, both the built-in one and ones generated by the wizard.
- `mail.enabled = false` makes the application fail to start.
- CRUD/forms:
   - Form invalid with empty, pristine date fields.
   - Save/update exception not handled properly.
   - Rich text field label misplacement.
   - Passwords visible in search results.
   - Possibility to save configuration with missing required fields.
   - Missing error message for max length in text fields.
   - IDs with spaces cause exception [[#254]](https://github.com/ManyDesigns/Portofino/issues/254).

## [5.0.2] - 2019-08-29

### Added
- Restored and extended some Portofino 4 features:
    - Numbers and dates can be searched with ranges as well as with an exact value.
    - Text properties can be searched with various operators (contains, equals, starts-with and ends-with).
    - Sign up, change password and forgot password dialogs and REST methods.
    - Password fields can ask to confirm the password (i.e., to type it twice).
- Improve developer experience with better code reloading:
    - Quartz jobs are reloaded automatically when the code changes, without restarting the application,
      and, when they terminate execution, any open Hibernate sessions are closed even in case of exceptions.
    - When source code changes, the user-defined Spring context is refreshed, so that services and actions can pick up the changes.
      This only works with classes annotated `@Component`, `@Repository` or `@Service`, to avoid excessive refreshes.
- When embedded, the crud page has now the option to open the detail in the same page instead of navigating to the detail URL.
- Check for new versions at startup.
- Make the JWT expiration time configurable (in minutes, defaults to 30).

### Changed
- UI improvements:
    - Improve looks by drawing inspiration from [sb-admin-material](https://github.com/start-javascript/sb-admin-material).
    - Use Material Typography.
    - The user declining to log in is sent back to the home. The current page has a chance to inject another behaviour.
    - Support the `multiplier` property of the `@DecimalFormat` annotation (for percent, per mille and similar).
    - The rich text component is better integrated in Material forms.
    - More comprehensive detection of links in text fields with `@HighlightLinks`.
    - The page settings panel is reachable via the URL, by including the query parameter `settings`.
- Important dependencies updated: Angular, Groovy, Liquibase, Shiro.

### Fixed
- Select fields with no value or disabled showing nothing or `undefined`.
- Create new page at the top level.
- Toolbar overflowing on mobile.
- Support BigInteger and BigDecimal properties in the UI.
- Properly save the crud page configuration.
- Use the correct schema name when synchronizing an aliased schema.

### Security
- Improved code quality and security and updated insecure dependencies using automated tools.

## [5.0.1] - 2019-06-07

### Added
- Created this changelog.
- Completed the translation to Italian.
- HQL queries support list parameters (ported from P4).

### Changed
- The no-frontend-build Maven profile skips all TypeScript/Angular builds without compromising the Java build.
- Keep the order of databases in the model (ported from P4).
- Updated to Angular 8.
- Logging out redirects to the home page.

### Fixed
- CRUD bulk operations detection by the UI.
- Inconsistent use of schemaName vs actualSchemaName.
- Default field encrypter (ported from P4).
- Many to many selection provider database session (ported from P4).
- Annotations not preserved when saving CRUD configuration and tables.

### Security
- Improved code quality and security using snyk, lgtm and SpotBugs to find vulnerabilities and brittle code.

Output:
【漏洞类型】JWT解析安全漏洞
【严重性】High
【漏洞摘要】原始代码使用`Jwts.parser().parse()`方法解析JWT，该方法在验证签名之前就返回了JWT对象。如果攻击者能够获取有效的JWT签名密钥，他们可以构造一个伪造的JWT并利用此漏洞访问系统。修复后的代码将JWT解析方法更改为`Jwts.parser().parseClaimsJws()`，该方法在返回JWT对象之前验证了签名，从而增强了安全性。
【关键代码模式】`Jwts.parser().parse()`
【修复方法说明】修复方法通过使用`Jwts.parser().parseClaimsJws()`来验证JWT签名，从而防止了伪造的JWT被利用访问系统。

Output:
【漏洞类型】路径遍历漏洞
【严重性】高
【漏洞摘要】这是一例路径遍历漏洞。原始代码中的`getSourceDocumentReference`函数使用`currentReferenceResolver.resolve(source)`来解析用户输入的`source`参数，该参数被用作文档引用。如果用户能够控制这个参数，他们可能会利用它来访问或操作不安全的文档，从而导致路径遍历攻击。

【关键代码模式】
- `getSourceDocumentReference`函数
- `currentReferenceResolver.resolve(source)`
- 用户输入的`source`参数

【修复方法说明】修复方法通过引入`AuthorizationManager`来检查用户是否具有对目标文档执行脚本的权限。如果用户没有该权限，则直接使用原始的`title`值，而不是尝试渲染它。这种方法通过确保只有授权用户才能执行Velocity脚本，从而解决了路径遍历漏洞。

Output:
【漏洞类型】信息泄露漏洞
【严重性】Medium
【漏洞摘要】原始代码在处理异常时，直接将用户输入的字符串值传递给`throwProcessingException`方法，用于错误消息中。这种做法可能会导致敏感信息（如用户输入）在错误日志中泄露。特别是当异常信息被记录在服务器日志中时，攻击者可以通过查看这些日志来获取用户的输入数据。
【关键代码模式】与异常处理和错误信息生成相关的代码模式，特别是：
- `extractValue`方法中的catch块
- `throwProcessingException`方法的调用
- 直接使用用户输入的字符串值生成错误消息

【修复方法说明】修复方法通过引入`_encode`函数，对用户输入的字符串值进行URL编码，以避免敏感信息泄露。这种方法遵循了“最小化信息泄露”的最佳实践，确保错误日志中不会泄露原始用户输入。
【最佳实践】使用`URLEncoder`对用户输入数据进行编码，以防止敏感信息泄露。在处理异常时，尽量避免直接将用户输入的数据包含在错误消息中。
