Chattycat est une maison d'édition jeunesse française dont l'ambition est de faire découvrir aux enfants l'anglais et la culture anglo-saxonne. Nous publions des romans, des BD et des livres d'activités bilingues pour la jeunesse. Notre concept ? Des histoires pleines d’aventures, des textes qui passent naturellement d’une langue à l’autre. L’enfant se plonge dans une histoire intéressante et apprend l’anglais presque sans s’en rendre compte ! Nos livres accompagnent le jeune lecteur à chaque étape de son enfance. L’anglais, mais pas seulement : Nos romans proposent une découverte culturelle et historique du monde anglophone. Et chaque livre contient des petits bonus : jeux, activités, chronologies historiques, carnets de voyage… Et bien sûr, une version audio accompagne chaque livre ! En parallèle de notre activité d'édition, Chattycat intervient dans les écoles, organisant des ateliers périscolaires. Les enfants créent leurs propres histoires, en anglais, que nous éditons pour eux dans un livre imprimé à la fin de l'année. Ces ateliers sont également donnés dans différentes formes en bibliothèque, en librairie et en centre de loisirs.

Description

ThingsBoard in versions prior to v4.2.1 allows an authenticated user to upload malicious SVG images via the "Image Gallery", leading to a Stored Cross-Site Scripting (XSS) vulnerability. The exploit can be triggered when any user accesses the public API endpoint of the malicious SVG images, or if the malicious images are embedded in an `iframe` element, during a widget creation, deployed to any page of the platform (e.g., dashboards), and accessed during normal operations. The vulnerability resides in the `ImageController`, which fails to restrict the execution of JavaScript code when an image is loaded by the user's browser. This vulnerability can lead to the execution of malicious code in the context of other users' sessions, potentially compromising their accounts and allowing unauthorized actions.
