+
+## Setup
+* [How to setup the plugin on your website](https://github.com/blueimp/jQuery-File-Upload/wiki/Setup)
+* [How to use only the basic plugin (minimal setup guide).](https://github.com/blueimp/jQuery-File-Upload/wiki/Basic-plugin)
+
+## Features
+* **Multiple file upload:**  
+  Allows to select multiple files at once and upload them simultaneously.
+* **Drag & Drop support:**  
+  Allows to upload files by dragging them from your desktop or file manager and dropping them on your browser window.
+* **Upload progress bar:**  
+  Shows a progress bar indicating the upload progress for individual files and for all uploads combined.
+* **Cancelable uploads:**  
+  Individual file uploads can be canceled to stop the upload progress.
+* **Resumable uploads:**  
+  Aborted uploads can be resumed with browsers supporting the Blob API.
+* **Chunked uploads:**  
+  Large files can be uploaded in smaller chunks with browsers supporting the Blob API.
+* **Client-side image resizing:**  
+  Images can be automatically resized on client-side with browsers supporting the required JS APIs.
+* **Preview images, audio and video:**  
+  A preview of image, audio and video files can be displayed before uploading with browsers supporting the required APIs.
+* **No browser plugins (e.g. Adobe Flash) required:**  
+  The implementation is based on open standards like HTML5 and JavaScript and requires no additional browser plugins.
+* **Graceful fallback for legacy browsers:**  
+  Uploads files via XMLHttpRequests if supported and uses iframes as fallback for legacy browsers.
+* **HTML file upload form fallback:**  
+  Allows progressive enhancement by using a standard HTML file upload form as widget element.
+* **Cross-site file uploads:**  
+  Supports uploading files to a different domain with cross-site XMLHttpRequests or iframe redirects.
+* **Multiple plugin instances:**  
+  Allows to use multiple plugin instances on the same webpage.

+  Files can be uploaded as standard "multipart/form-data" or file contents stream (HTTP PUT file upload).
+* **Compatible with any server-side application platform:**  
+  Works with any server-side platform (PHP, Python, Ruby on Rails, Java, Node.js, Go etc.) that supports standard HTML form file uploads.
+
+## Requirements
+
+### Mandatory requirements
+* [jQuery](https://jquery.com/) v. 1.6+
+* [jQuery UI widget factory](https://api.jqueryui.com/jQuery.widget/) v. 1.9+ (included): Required for the basic File Upload plugin, but very lightweight without any other dependencies from the jQuery UI suite.
+* [jQuery Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js) (included): Required for [browsers without XHR file upload support](https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support).
+
+### Optional requirements
+* [JavaScript Templates engine](https://github.com/blueimp/JavaScript-Templates) v. 2.5.4+: Used to render the selected and uploaded files for the Basic Plus UI and jQuery UI versions.
+* [JavaScript Load Image library](https://github.com/blueimp/JavaScript-Load-Image) v. 1.13.0+: Required for the image previews and resizing functionality.
+* [JavaScript Canvas to Blob polyfill](https://github.com/blueimp/JavaScript-Canvas-to-Blob) v. 2.1.1+:Required for the image previews and resizing functionality.
+* [blueimp Gallery](https://github.com/blueimp/Gallery) v. 2.15.1+: Used to display the uploaded images in a lightbox.
+* [Bootstrap](http://getbootstrap.com/) v. 3.2.0+
+* [Glyphicons](http://glyphicons.com/)
+
+The user interface of all versions, except the jQuery UI version, is built with [Bootstrap](http://getbootstrap.com/) and icons from [Glyphicons](http://glyphicons.com/).
+
+### Cross-domain requirements
+[Cross-domain File Uploads](https://github.com/blueimp/jQuery-File-Upload/wiki/Cross-domain-uploads) using the [Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js) require a redirect back to the origin server to retrieve the upload results. The [example implementation](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/main.js) makes use of [result.html](https://github.com/blueimp/jQuery-File-Upload/blob/master/cors/result.html) as a static redirect page for the origin server.
+
+The repository also includes the [jQuery XDomainRequest Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/cors/jquery.xdr-transport.js), which enables limited cross-domain AJAX requests in Microsoft Internet Explorer 8 and 9 (IE 10 supports cross-domain XHR requests).  
+The XDomainRequest object allows GET and POST requests only and doesn't support file uploads. It is used on the [Demo](https://blueimp.github.io/jQuery-File-Upload/) to delete uploaded files from the cross-domain demo file upload service.
+
+### Custom Backends
+
+You can add support for various backends by adhering to the specification [outlined here](https://github.com/blueimp/jQuery-File-Upload/wiki/JSON-Response).
+

+# File Upload Security
+For an in-depth understanding of the potential security risks of providing file uploads and possible mitigations, please refer to the [OWASP  - Unrestricted File Upload](https://www.owasp.org/index.php/Unrestricted_File_Upload) documentation.
+
+To securely setup the project to serve uploaded files, please refer to the sample [Secure file upload serving configurations](#secure-file-upload-serving-configurations).
+
+To mitigate potential vulnerabilities in image processing libraries, please refer to the [Secure image processing configurations](#secure-image-processing-configurations).
+
+By default, all sample upload handlers allow only upload of image files, which mitigates some attack vectors, but should not be relied on as the only protection.
+
+Please also have a look at the [list of fixed vulnerabilities](VULNERABILITIES.md) in jQuery File Upload, which relates mostly to the sample server-side upload handlers and how they have been configured.
+
+## Purpose of this project
+Please note that this project is not a complete file management product, but foremost a client-side file upload library for [jQuery](https://jquery.com/).  
+The server-side sample upload handlers are just examples to demonstrate the client-side file upload functionality.
+
+To make this very clear, there is **no user authentication** by default:
+* **everyone can upload files**
+* **everyone can delete uploaded files**
+
+In some cases this can be acceptable, but for most projects you will want to extend the sample upload handlers to integrate user authentication, or implement your own.
+
+It is also up to you to configure your Webserver to securely serve the uploaded files, e.g. using the [sample server configurations](#secure-file-upload-serving-configurations).
+
+## Mitigations against file upload risks
+
+### Prevent code execution on the server
+To prevent execution of scripts or binaries on server-side, the upload directory must be configured to not execute files in the upload directory (e.g. `server/php/files` as the default for the PHP upload handler) and only treat uploaded files as static content.
+
+The recommended way to do this is to configure the upload directory path to point outside of the web application root.  
+Then the Webserver can be configured to serve files from the upload directory with their default static files handler only.
+
+Limiting file uploads to a whitelist of safe file types (e.g. image files) also mitigates this issue, but should not be the only protection.
+
+### Prevent code execution in the browser
+To prevent execution of scripts on client-side, the following headers must
+be sent when delivering generic uploaded files to the client:
+
+```
+Content-Type: application/octet-stream
+X-Content-Type-Options: nosniff
+```
+
+The `Content-Type: application/octet-stream` header instructs browsers to display a download dialog instead of parsing it and possibly executing script content e.g. in HTML files.
+
+The `X-Content-Type-Options: nosniff` header prevents browsers to try to detect the file mime type despite the given content-type header.
+
+For known safe files, the content-type header can be adjusted using a **whitelist**, e.g. sending `Content-Type: image/png` for PNG files.
+
+### Prevent distribution of malware
+To prevent attackers from uploading and distributing malware (e.g. computer viruses), it is recommended to limit file uploads only to a whitelist of safe file types.
+
+Please note that the detection of file types in the sample file upload handlers is based on the file extension and not the actual file content. This makes it still possible for attackers to upload malware by giving their files an image file extension, but should prevent automatic execution on client computers when opening those files.
+
+It does not protect at all from exploiting vulnerabilities in image display programs, nor from users renaming file extensions to inadvertently execute the contained malicious code.
+
+## Secure file upload serving configurations
+The following configurations serve uploaded files as static files with the proper headers as [mitigation against file upload risks](#mitigations-against-file-upload-risks).  
+Please do not simply copy&paste these configurations, but make sure you understand what they are doing and that you have implemented them correctly.
+
+> Always test your own setup and make sure that it is secure!
+
+e.g. try uploading PHP scripts (as "example.php", "example.php.png" and "example.png") to see if they get executed by your Webserver.
+
+### Apache config
+Add the following directive to the Apache config, replacing the directory path with the absolute path to the upload directory:
+
+```ApacheConf
+<Directory "/path/to/project/server/php/files">
+  # To enable the Headers module, execute the following command and reload Apache:
+  # sudo a2enmod headers
+
+  # The following directives prevent the execution of script files
+  # in the context of the website.
+  # They also force the content-type application/octet-stream and
+  # force browsers to display a download dialog for non-image files.
+  SetHandler default-handler
+  ForceType application/octet-stream
+  Header set Content-Disposition attachment
+
+  # The following unsets the forced type and Content-Disposition headers
+  # for known image files:
+  <FilesMatch "(?i)\.(gif|jpe?g|png)$">
+    ForceType none
+    Header unset Content-Disposition
+  </FilesMatch>
+
+  # The following directive prevents browsers from MIME-sniffing the content-type.
+  # This is an important complement to the ForceType directive above:
+  Header set X-Content-Type-Options nosniff
+</Directory>
+```
+
+### NGINX config
+Add the following directive to the NGINX config, replacing the directory path with the absolute path to the upload directory:
+
+```Nginx
+location ^~ /path/to/project/server/php/files {
+    root html;
+    default_type application/octet-stream;
+    types {
+        image/gif     gif;
+        image/jpeg    jpg;
+        image/png    png;
+    }
+    add_header X-Content-Type-Options 'nosniff';
+    if ($request_filename ~ /(((?!\.(jpg)|(png)|(gif)$)[^/])+$)) {
+        add_header Content-Disposition 'attachment; filename="$1"';
+        # Add X-Content-Type-Options again, as using add_header in a new context
+        # dismisses all previous add_header calls:
+        add_header X-Content-Type-Options 'nosniff';
+    }
+}
+```
+
+## Secure image processing configurations
+The following configuration mitigates [potential image processing vulnerabilities with ImageMagick](VULNERABILITIES.md#potential-vulnerabilities-with-php+imagemagick) by limiting the attack vectors to a small subset of image types (`GIF/JPEG/PNG`).
+
+Please also consider using alternative, safer image processing libraries like [libvips](https://github.com/libvips/libvips) or [imageflow](https://github.com/imazen/imageflow).
+
+## ImageMagick config
+It is recommended to disable all non-required ImageMagick coders via [policy.xml](https://wiki.debian.org/imagemagick/security).  
+To do so, locate the ImageMagick `policy.xml` configuration file and add the following policies:
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<!-- ... -->
+<policymap>
+  <!-- ... -->
+  <policy domain="delegate" rights="none" pattern="*" />
+  <policy domain="coder" rights="none" pattern="*" />
+  <policy domain="coder" rights="read | write" pattern="{GIF,JPEG,PNG}" />
+</policymap>
+```

+# ⚠️ List of fixed vulnerabilities
+
+## Potential vulnerabilities with PHP+ImageMagick
+> Mitigated: 2018-10-25 (GMT)
+
+The sample [PHP upload handler](server/php/UploadHandler.php) before [v9.25.1](https://github.com/blueimp/jQuery-File-Upload/releases/tag/v9.25.1) did not validate file signatures before invoking [ImageMagick](https://www.imagemagick.org/) (via [Imagick](http://php.net/manual/en/book.imagick.php)).  
+Verifying those [magic bytes](https://en.wikipedia.org/wiki/List_of_file_signatures) mitigates potential vulnerabilities when handling input files other than `GIF/JPEG/PNG`.
+
+Please also configure ImageMagick to only enable the coders required for `GIF/JPEG/PNG` processing, e.g. with the sample [ImageMagick config](SECURITY.md#imagemagick-config).
+

+
+## Remote code execution vulnerability in the PHP component
+> Fixed: 2018-10-23 (GMT)
+
+The sample [PHP upload handler](server/php/UploadHandler.php) before [v9.24.1](https://github.com/blueimp/jQuery-File-Upload/releases/tag/v9.24.1) allowed to upload all file types by default.  
+This opens up a remote code execution vulnerability, unless the server is configured to not execute (PHP) files in the upload directory (`server/php/files`).  
+
+The provided [.htaccess](server/php/files/.htaccess) file includes instructions for Apache to disable script execution, however [.htaccess support](https://httpd.apache.org/docs/current/howto/htaccess.html) is disabled by default since Apache `v2.3.9` via [AllowOverride Directive](https://httpd.apache.org/docs/current/mod/core.html#allowoverride).
+
+**You are affected if you:**
+1. A) Uploaded jQuery File Upload < `v9.24.1` on a Webserver that executes files with `.php` as part of the file extension (e.g. "example.php.png"), e.g. Apache with `mod_php` enabled and the following directive (*not a recommended configuration*):
+    ```ApacheConf
+    AddHandler php5-script .php
+    ```
+   B) Uploaded jQuery File Upload < `v9.22.1` on a Webserver that executes files with the file extension `.php`, e.g. Apache with `mod_php` enabled and the following directive:
+    ```ApacheConf
+    <FilesMatch \.php$>
+      SetHandler application/x-httpd-php
+    </FilesMatch>
+    ```
+2. Did not actively configure your Webserver to not execute files in the upload directory (`server/php/files`).
+3. Are running Apache `v2.3.9+` with the default `AllowOverride` Directive set to `None` or another Webserver with no `.htaccess` support.
+
+**How to fix it:**
+1. Upgrade to the latest version of jQuery File Upload.
+2. Configure your Webserver to not execute files in the upload directory, e.g. with the [sample Apache configuration](SECURITY.md#apache-config)

+
+## Open redirect vulnerability in the GAE components
+> Fixed: 2015-06-12 (GMT)
+
+The sample Google App Engine upload handlers before v[9.10.1](https://github.com/blueimp/jQuery-File-Upload/releases/tag/9.10.1) accepted any URL as redirect target, making it possible to use the Webserver's domain for phishing attacks.

+
+## Cross-site scripting vulnerability in the Iframe Transport
+> Fixed: 2012-08-09 (GMT)
+
+The [redirect page](cors/result.html) for the [Iframe Transport](js/jquery.iframe-transport.js) before commit [4175032](https://github.com/blueimp/jQuery-File-Upload/commit/41750323a464e848856dc4c5c940663498beb74a) (*fixed in all tagged releases*) allowed executing arbitrary JavaScript in the context of the Webserver.
