La soci\u00e9t\u00e9 Google a d\u00e9cid\u00e9 de supprimer du moteur de navigation Chromium les composants pour le support du langage de transformation de documents XML XSLT. La raison invoqu\u00e9e est le souhait de r\u00e9duire la surface d'attaque en abandonnant l'utilisation de la biblioth\u00e8que libxslt. Selon Google, le support de XSLT 1.0 cr\u00e9e des risques de s\u00e9curit\u00e9 injustifi\u00e9s, car des vuln\u00e9rabilit\u00e9s (comme CVE-2025-7425 et CVE-2022-22834) sont r\u00e9guli\u00e8rement d\u00e9tect\u00e9es dans la biblioth\u00e8que libxslt, qui a \u00e9galement des probl\u00e8mes de maintenance (de juin \u00e0 septembre, la biblioth\u00e8que est rest\u00e9e sans support ni correction des vuln\u00e9rabilit\u00e9s). Les projets Firefox et WebKit envisagent \u00e9galement de supprimer le support de XSLT. <\/p>\n
Les vuln\u00e9rabilit\u00e9s dans XSLT deviennent un outil pour mener des attaques sur les navigateurs, alors que le support client de XSLT est actuellement peu demand\u00e9 et utilis\u00e9 tr\u00e8s rarement, et que les t\u00e2ches de transformation de donn\u00e9es en HTML peuvent \u00eatre r\u00e9alis\u00e9es de mani\u00e8re plus s\u00e9curis\u00e9e gr\u00e2ce \u00e0 des API JavaScript, comme DOMParser et Fetch. Selon les statistiques de Google, la part des pages Web charg\u00e9es utilisant XSLT est de 0,02 %, tandis que la part des pages sur lesquelles des instructions de traitement XSLT sont appliqu\u00e9es est estim\u00e9e \u00e0 0,001 %. <\/p>\n
Il a \u00e9galement \u00e9t\u00e9 d\u00e9cid\u00e9 de cesser d'utiliser la biblioth\u00e8que libxml2 dans Chromium, qui pr\u00e9sente r\u00e9guli\u00e8rement des vuln\u00e9rabilit\u00e9s et des probl\u00e8mes de maintenance. La biblioth\u00e8que libxml2 est utilis\u00e9e dans Chromium pour l'analyse, la s\u00e9rialisation et la validation des donn\u00e9es au format XML, tandis que la classe XSLTProcessor et les instructions de traitement XSLT () sont bas\u00e9es sur libxslt. <\/p>\n
Le support des fonctionnalit\u00e9s bas\u00e9es sur libxslt, comme l'API XSLTProcessor et les instructions d'analyse des feuilles de style XML, sera interrompu dans la version Chrome 155, pr\u00e9vue pour le 17 novembre 2026. Dans Chrome 143, pr\u00e9vu pour le 2 d\u00e9cembre 2025, un avertissement sera ajout\u00e9 dans la console Web concernant la mise de l'API XSLTProcessor en mode obsol\u00e8te. Dans Chrome 148 (au printemps 2026), le support de XSLT sera d\u00e9sactiv\u00e9 par d\u00e9faut dans les branches Canary, Dev et Beta. La fonctionnalit\u00e9 d'analyse XML sera conserv\u00e9e, mais transf\u00e9r\u00e9e vers une nouvelle biblioth\u00e8que \u00e9crite en Rust, avec un accent sur la s\u00e9curit\u00e9. <\/p>\n
En tant que remplacement du support XSLT int\u00e9gr\u00e9 au navigateur, il est propos\u00e9 de transf\u00e9rer le traitement XSLT c\u00f4t\u00e9 de serveurs<\/a> et d'envoyer aux clients le contenu HTML d\u00e9j\u00e0 form\u00e9. Les gestionnaires utilisant l'API XML pour l'interaction entre le client et serveur<\/a>, il est propos\u00e9 de remplacer par l'utilisation du format JSON et le rendu via la transformation de JSON en HTML\/CSS \u00e0 l'aide de JavaScript. Parmi les alternatives possibles, on note \u00e9galement l'utilisation de biblioth\u00e8ques JavaScript comme Saxonica pour l'impl\u00e9mentation de XSLT, ainsi qu'une couche polyfill pour assurer la compatibilit\u00e9 avec l'ancien code, proposant de remplacer XSLTProcessor bas\u00e9 sur WASM, et une extension de navigateur qui ins\u00e8re automatiquement la couche polyfill dans les documents XML. \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Google \u043f\u0440\u0438\u043d\u044f\u043b\u0430 \u0440\u0435\u0448\u0435\u043d\u0438\u0435 \u0443\u0434\u0430\u043b\u0438\u0442\u044c
