Spole\u010dnost Google se rozhodla odstranit z prohl\u00ed\u017ee\u010de Chromium komponenty pro podporu jazyka pro transformaci XML dokument\u016f XSLT.

CVE-2025-7425 a CVE-2022-22834) a m\u00e1 probl\u00e9my s podp\u016frn\u00fdmi slu\u017ebami (od \u010dervna do z\u00e1\u0159\u00ed z\u016fstala knihovna bez podpory a opravy zranitelnost\u00ed).

Zranitelnosti v XSLT se st\u00e1vaj\u00ed n\u00e1strojem pro \u00fatoky na prohl\u00ed\u017ee\u010de, p\u0159i\u010dem\u017e v sou\u010dasnosti je klientsk\u00e1 podpora XSLT nepou\u017e\u00edvan\u00e1 a je vyu\u017e\u00edv\u00e1na velmi z\u0159\u00eddka, zat\u00edmco \u00fakoly transformace dat do HTML mohou b\u00fdt bezpe\u010dn\u011bji prov\u00e1d\u011bny pomoc\u00ed API JavaScriptu, jako jsou DOMParser a Fetch.

Podobn\u011b bylo rozhodnuto ukon\u010dit pou\u017e\u00edv\u00e1n\u00ed knihovny libxml2 v Chromiu, ve kter\u00e9 jsou tak\u00e9 pravideln\u011b nalezeny zranitelnosti a jsou probl\u00e9my s \u00fadr\u017ebou. Knihovna libxml2 se pou\u017e\u00edv\u00e1 v Chromiu pro anal\u00fdzu, serializaci a ov\u011b\u0159ov\u00e1n\u00ed dat ve form\u00e1tu XML, a na z\u00e1klad\u011b libxslt je realizov\u00e1na t\u0159\u00edda XSLTProcessor a pokyny pro zpracov\u00e1n\u00ed XSLT («<?xml-stylesheet … ?>»). <\/p>\n
Podpora funkc\u00ed zalo\u017een\u00fdch na libxslt, jako jsou API XSLTProcessor a instrukce pro anal\u00fdzu XML styl\u016f, bude ukon\u010dena v verzi Chrome 155, pl\u00e1novan\u00e9 na 17. listopadu 2026.

Funk\u010dnost pro anal\u00fdzu XML z\u016fstane, ale bude p\u0159evedena na novou knihovnu napsanou v jazyce Rust s ohledem na zaji\u0161t\u011bn\u00ed bezpe\u010dnosti. <\/p>\n
Jako n\u00e1hradu za vestav\u011bnou podporu XSLT v prohl\u00ed\u017ee\u010di se navrhuje p\u0159esunout zpracov\u00e1n\u00ed XSLT na stranu serveru<\/a> a pos\u00edlat klient\u016fm ji\u017e vytvo\u0159en\u00fd HTML obsah.
