Résumé
rhukster/dom-sanitizer: SVG <style> tag allows CSS injection via unfiltered url() and @import directives
Description d'origine
La description telle que publiée par la source (souvent en anglais).
DOMSanitizer is a DOM/SVG/MathML Sanitizer for PHP 7.3+. Prior to version 1.0.10, DOMSanitizer::sanitize() allows elements in SVG content but never inspects their text content. CSS url() references and @import rules pass through unfiltered, causing the browser to issue HTTP requests to attacker-controlled hosts when the sanitized SVG is rendered. Version 1.0.10 fixes the issue.
