Output:
【漏洞类型】业务逻辑安全漏洞
【严重性】Medium
【漏洞摘要】原始代码在创建XWikiComments文档的类时，调用`xclass.addTextAreaField`方法时没有设置`restricted`参数。这意味着在XWiki中，用户可以上传任何内容到这个字段中，包括潜在的恶意代码或脚本。这可能会导致跨站脚本攻击（XSS）或其他业务逻辑安全问题。
【关键代码模式】`xclass.addTextAreaField`方法在调用时没有设置`restricted`参数。
【修复方法说明】修复方法通过在`xclass.addTextAreaField`方法中添加`true`参数来设置`restricted`，从而防止用户上传恶意内容，减少了XSS攻击的风险。

# Markdown to PDF

[![Github Actions Badge](https://github.com/simonhaenisch/md-to-pdf/workflows/Node%20CI/badge.svg)](https://github.com/simonhaenisch/md-to-pdf/actions)
[![NPM version](https://img.shields.io/npm/v/md-to-pdf.svg)](https://www.npmjs.com/md-to-pdf)
[![XO code style](https://img.shields.io/badge/code_style-XO-5ed9c7.svg)](https://github.com/xojs/xo)

![Screenshot of markdown file and resulting PDF](https://files-iiiuxybjc.now.sh)

**A simple and hackable CLI tool for converting markdown to pdf**. It uses [Marked](https://github.com/markedjs/marked) to convert `markdown` to `html` and [Puppeteer](https://github.com/GoogleChrome/puppeteer) (headless Chromium) to further convert the `html` to `pdf`. It also uses [highlight.js](https://github.com/isagalaev/highlight.js) for code highlighting. The whole source code of this tool is ~only \~250 lines of JS~ ~400 lines of Typescript and ~100 lines of CSS, so it is easy to clone and customize.

**Highlights:**

- Concurrently convert multiple Markdown files
- Watch mode
- Use your own or remote stylesheets/scripts
- Front-matter for configuration
- Headers and Footers
- Page Breaks
- Syntax highlighting in code blocks
- Extend the options of the underlying tools
- Programmatic API
- Supports `stdio`

## Installation

**Option 1: NPM**

```sh
npm i -g md-to-pdf
```

**Option 2: Git**

If you want to have your own copy to hack around with, clone the repository instead:

```sh
git clone "https://github.com/simonhaenisch/md-to-pdf"
cd md-to-pdf
npm link # or npm i -g
```

Then the commands `md-to-pdf` and `md2pdf` (as a shorthand) will be globally available in your cli. Use `npm start` to start the TypeScript compiler (`tsc`) in watch mode.

## Update

If you installed via npm, run `npm i -g md-to-pdf@latest` in your CLI. If you cloned this repository instead, you can simply do a `git pull` to get the latest changes from the master branch, then do `npm run build` to re-build. Unless there have been changes to packages (i. e. `package-lock.json`), you don't need to re-install the package (because NPM 5+ uses symlinks, at least on Unix systems).

## Usage

```
$ md-to-pdf [options] path/to/file.md

Options:

  -h, --help ............... Output usage information
  -v, --version ............ Output version
  -w, --watch .............. Watch the current file(s) for changes
  --watch-options .......... Options for Chokidar's watch call
  --basedir ................ Base directory to be served by the file server
  --stylesheet ............. Path to a local or remote stylesheet (can be passed multiple times)
  --css .................... String of styles
  --document-title ......... Name of the HTML Document.
  --body-class ............. Classes to be added to the body tag (can be passed multiple times)
  --page-media-type ........ Media type to emulate the page with (default: screen)
  --highlight-style ........ Style to be used by highlight.js (default: github)
  --marked-options ......... Set custom options for marked (as a JSON string)
  --pdf-options ............ Set custom options for the generated PDF (as a JSON string)
  --launch-options ......... Set custom launch options for Puppeteer
  --port ................... Set the port to run the http server on
  --md-file-encoding ....... Set the file encoding for the markdown file
  --stylesheet-encoding .... Set the file encoding for the stylesheet
  --as-html ................ Output as HTML instead
  --config-file ............ Path to a JSON or JS configuration file
  --devtools ............... Open the browser with devtools instead of creating PDF
```

The pdf is generated into the same directory as the source file and uses the same filename (with `.pdf` extension) by default. Multiple files can be specified by using shell globbing, e. g.:

```sh
md-to-pdf ./**/*.md
```

_(If you use bash, you might need to enable the `globstar` shell option to make recursive globbing work.)_

Alternatively, you can pass the markdown in from `stdin` and pipe its `stdout` into a target file:

```sh
cat file.md | md-to-pdf > path/to/output.pdf
```

_Tip: You can concatenate multiple files using `cat file1.md file2.md`._

The current working directory (`process.cwd()`) serves as the base directory of the file server by default. This can be adjusted with the `--basedir` flag (or equivalent config option).

#### Watch Mode

Watch mode (`--watch`) uses Chokidar's `watch` method on the markdown file. If you're having issues, you can adjust the watch options via the config (`watch_options`) or `--watch-options` CLI arg. The `awaitWriteFinish` option might be particularly useful if you use editor plugins (e. g. TOC generators) that modify and save the file after the initial save. Check out the [Chokidar docs](https://github.com/paulmillr/chokidar#api) for a full list of options.

Note that Preview on macOS does not automatically reload the preview when the file has changed (or at least not reliably). There are PDF viewers available that can check for file changes and offer auto-reload (e. g. [Skim](https://skim-app.sourceforge.io/)'s "Sync" feature).

#### Programmatic API

The programmatic API is very simple: it only exposes one function that accepts either a `path` to or `content` of a markdown file, and an optional config object (which can be used to specify the output file destination).

```js
const fs = require('fs');
const { mdToPdf } = require('md-to-pdf');

(async () => {
	const pdf = await mdToPdf({ path: 'readme.md' }).catch(console.error);

	if (pdf) {
		fs.writeFileSync(pdf.filename, pdf.content);
	}
})();
```

The function throws an error if anything goes wrong, which can be handled by catching the rejected promise. If you set the `dest` option in the config, the file will be written to the specified location straight away:

```js
await mdToPdf({ content: '# Hello, World' }, { dest: 'path/to/output.pdf' });
```

#### Page Break

Place an element with class `page-break` to force a page break at a certain point of the document (uses the CSS rule `page-break-after: always`), e. g.:

```html
<div class="page-break"></div>
```

#### Header/Footer

Use `headerTemplate` and `footerTemplate` of Puppeteer's [`page.pdf()` options](https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagepdfoptions). If either of the two is set, then `displayHeaderFooter` will be enabled by default. It's possible to inject a few dynamic values like page numbers by using certain class names, as stated in the Puppeteer docs. Please note that for some reason the font-size defaults to 1pt, and you need to make sure to have enough page margin, otherwise your header/footer might be overlayed by your content. If you add a `<style/>` tag in either of the templates, it will be applied to both header and footer.

Example markdown frontmatter config that prints the date in the header and the page number in the footer:

```markdown
---
pdf_options:
  format: a4
  margin: 30mm 20mm
  printBackground: true
  headerTemplate: |-
    <style>
      section {
        margin: 0 auto;
        font-family: system-ui;
        font-size: 11px;
      }
    </style>
    <section>
      <span class="title"></span>
      <span class="date"></span>
    </section>
  footerTemplate: |-
    <section>
      <div>
        Page <span class="pageNumber"></span>
        of <span class="totalPages"></span>
      </div>
    </section>
---
```

Refer to the [Puppeteer docs](https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagepdfoptions) for more info about headers and footers.

#### Formulas

This can be achieved with [MathJax](https://www.mathjax.org/). A simple example can be found in [`/src/test/mathjax`](/src/test/mathjax).

#### Default and Advanced Options

For default and advanced options see the following links. The default highlight.js styling for code blocks is `github`. The default PDF options are the A4 format and some margin (see `lib/config.ts` for the full default config).

- [Marked Advanced Options](https://github.com/markedjs/marked/blob/master/docs/USING_ADVANCED.md)
- [Puppeteer PDF Options](https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagepdfoptions)
- [Puppeteer Launch Options](https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#puppeteerlaunchoptions)
- [highlight.js Styles](https://github.com/isagalaev/highlight.js/tree/master/src/styles)

**`margin`:** instead of an object (as stated in the Puppeteer docs), it is also possible to pass a CSS-like string, e. g. `1em` (all), `1in 2in` (top/bottom right/left), `10mm 20mm 30mm` (top right/left bottom) or `1px 2px 3px 4px` (top right bottom left).

**`highlight-style`:** if you set a highlight style with a background color, make sure that `"printBackground": true` is set in the pdf options.

The options can also be set with front-matter or a config file (except `--md-file-encoding` can't be set by front-matter). In that case, remove the leading two hyphens (`--`) from the cli argument name and replace the hyphens (`-`) with underscores (`_`). `--stylesheet` and `--body-class` can be passed multiple times (i. e. to create an array). It's possible to set the output path for the PDF as `dest` in the config. If the same config option exists in multiple places, the priority (from low to high) is: defaults, config file, front-matter, cli arguments.

Example front-matter:

```markdown
---
dest: ./path/to/output.pdf
stylesheet:
  - path/to/style.css
body_class: markdown-body
highlight_style: monokai
pdf_options:
  format: A5
  margin: 10mm
  printBackground: true
---

# Content
```

The config file can be a Javascript file that exports a config object, which gives you the full power of the eco-system (e. g. for advanced header/footer templates); or it can also be a `.json` if you like it simple.

Example `config.js`:

```js
module.exports = {
	stylesheet: ['path/to/style.css', 'https://example.org/stylesheet.css'],
	css: `body { color: tomato; }`,
	body_class: 'markdown-body',
	marked_options: {
		headerIds: false,
		smartypants: true,
	},
	pdf_options: {
		format: 'A5',
		margin: '20mm',
		printBackground: true,
	},
	stylesheet_encoding: 'utf-8',
};
```

Example `config.json`:

```json
{
	"highlight_style": "monokai",
	"body_class": ["dark", "content"]
}
```

#### Github Styles

Here is an example front-matter for how to get Github-like output:

```markdown
---
stylesheet: https://cdnjs.cloudflare.com/ajax/libs/github-markdown-css/2.10.0/github-markdown.min.css
body_class: markdown-body
css: |-
  .page-break { page-break-after: always; }
  .markdown-body { font-size: 11px; }
  .markdown-body pre > code { white-space: pre-wrap; }
---
```

## Security Consideration

By default, this tool serves the current working directory via a http server on `localhost` on a relatively random port (or the port you specify), and that server gets shut down when the process exits (or as soon as it is killed). Please be aware that for the duration of the process this server will be accessible on your local network, and therefore all files within the served folder that the process has permission to read. So as a suggestion, maybe don't run this in watch mode in your system's root folder. 😉

## Customization/Development

After cloning and linking/installing globally (`npm link`), just run the transpiler in watch mode (`npm start`). Then you can start making changes to the files and Typescript will transpile them on save. NPM 5+ uses symlinks for locally installed global packages, so all changes are reflected immediately without needing to re-install the package (except when there have been changes to required packages, then re-install using `npm i`). This also means that you can just do a `git pull` to get the latest version onto your machine.

Ideas, feature requests and PRs are welcome. Just keep it simple! 🤓

Output:
【漏洞类型】远程代码执行（RCE）
【严重性】High
【漏洞摘要】此代码存在远程代码执行漏洞，主要问题在于`gray-matter`库的默认配置允许执行JavaScript代码。攻击者可以通过在Markdown文件中注入恶意的front-matter来执行任意JavaScript代码，从而导致潜在的RCE风险。具体表现为在`src/lib/md-to-pdf.ts`文件中，`grayMatter`函数没有经过任何验证就直接解析了Markdown文件的内容，允许执行JavaScript。

【关键代码模式】
- `gray-matter`库的使用
- front-matter的解析和执行

【修复方法说明】修复方法通过默认禁用`gray-matter`库的JavaScript引擎来防止RCE攻击。具体实现是通过在`defaultConfig`中设置`gray_matter_options`来禁用JS引擎，并在`convertMdToPdf`函数中检查并处理front-matter解析的结果。

Output:
【漏洞类型】数组越界漏洞
【严重性】High
【漏洞摘要】原始代码在处理加密和解密操作时，未对输入参数进行充分验证，可能导致数组越界异常。具体表现为在`encryptWithAd`和`decryptWithAd`方法中，`ciphertextOffset`和`plaintextOffset`未进行负数检查，这在某些情况下可能导致数组越界异常。根本原因在于对数组长度的检查不够全面，没有考虑到负数偏移的可能性。
【关键代码模式】与漏洞相关的关键代码模式包括`ciphertextOffset`和`plaintextOffset`在`encryptWithAd`和`decryptWithAd`方法中的使用。关键词包括`Arrays.fill`、`System.arraycopy`、`aes.encrypt`、`cipher.update`等。
【修复方法说明】修复方法通过在`encryptWithAd`和`decryptWithAd`方法中添加负数检查来解决数组越界问题。最佳实践是始终验证数组长度和偏移量，以防止潜在的数组越界异常。

Output:
【漏洞类型】非法输入验证漏洞
【严重性】Medium
【漏洞摘要】原始代码中，`Namespace` 和 `QName` 类并未对传入的名称（如 `prefix`、`uri`、`name`、`qualifiedName`）进行充分的验证，允许传入不符合 XML 规范的名称，这可能导致 XML 解析器在处理这些名称时出现问题，例如拒绝服务攻击（DoS）或 XML 外部实体（XXE）攻击。
【关键代码模式】
- `Namespace` 类的构造函数中对 `prefix` 和 `uri` 的检查（`if (prefix != null) { this.prefix = prefix; }` 和 `if (uri != null) { this.uri = uri; }`）。
- `QName` 类的构造函数中对 `name` 和 `qualifiedName` 的检查（`this.name = (name == null) ? "" : name;` 和 `this.qualifiedName = qualifiedName;`）。
- 未使用正则表达式或其他验证机制来确保传入的名称符合 XML 的命名规则。
【修复方法说明】修复方法通过添加正则表达式验证来确保传入的名称符合 XML 的命名规则，从而防止非法输入导致的安全问题。

Output:
【漏洞类型】权限绕过漏洞

【严重性】High

【漏洞摘要】原始代码中，`BaseUserController` 和 `GroupController` 中的某些方法没有进行足够的权限校验，允许用户访问或修改他们无权访问或修改的资源。例如，在 `BaseUserController` 的 `getCurrentWorkspaceMember`、`getProjectMemberListAll` 和 `getProjectMembers` 方法中，用户可以请求任意工作空间或项目的成员列表，而没有检查用户是否属于该工作空间或项目。在 `GroupController` 中，`getAllUserGroup` 方法没有权限校验，允许任何用户获取任意用户的组信息。

【关键代码模式】
- 未进行权限校验的方法，例如 `getCurrentWorkspaceMember`、`getProjectMemberListAll`、`getProjectMembers` 和 `getAllUserGroup`。
- 使用 `SessionUtils` 获取当前用户信息，但未进一步验证用户对请求资源的访问权限。
- 缺少对用户输入的验证或限制，允许用户请求任意资源。

【修复方法说明】
- 修复方法通过在关键代码中添加权限校验逻辑，确保用户只能访问或修改他们有权限的资源。
- 适用的最佳实践是使用细粒度的权限控制，确保每个用户只能操作其有权限的数据。

【漏洞类型】安全漏洞类型名称
【严重性】Medium
【漏洞摘要】这是一个安全漏洞，具体表现为在代码中使用了用户输入作为错误信息模板。这可能导致任意表达式语言（EL）表达式执行，因为某些验证框架允许在错误信息中嵌入表达式，而这些表达式可以被恶意用户操纵。问题行在修复代码中是`context.buildConstraintViolationWithTemplate("Error parsing the Cron expression").addConstraintViolation();`，在原始代码中则是`context.buildConstraintViolationWithTemplate(e.getMessage()).addConstraintViolation();`。
【关键代码模式】与漏洞相关的关键代码模式包括用户输入的使用、错误信息的构建以及可能的EL表达式执行。
【修复方法说明】修复方法通过将具体的异常信息替换为通用的错误信息，防止了恶意用户通过错误信息中的表达式执行任意代码。最佳实践包括对用户输入进行严格的验证和对错误信息进行安全处理，以避免潜在的安全风险。
