+Bonjour, je suis une application vulnerable qui sert a inserer des chaines dans une base de données MySQL!

+<p>
+Liste des chaines actuellement insérées:
+<ul>
+'''+"\n".join(["<li>" + s + "</li>" for s in chaines])+'''
+</ul>
+</p>
+<p> Inserer une chaine:
+<form method="post" onsubmit="return validate()">
+<input type="text" name="chaine" id="chaine" value="" />
+<br />
+<input type="submit" name="submit" value="OK" />
+</form>
+<script>
+function validate() {
+    var regex = /^[a-zA-Z0-9]+$/;
+    var chaine = document.getElementById('chaine').value;
+    console.log(regex.test(chaine));
+    if (!regex.test(chaine)) {
