+## 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](https://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.
