CVE-2026-41591— marko 跨站脚本漏洞

Marko: XSS via case-insensitive script/style closing tag bypass in runtime HTML escaping

Marko is a declarative, HTML-based language for building web apps. Prior to marko version 5.38.36 and prior to @marko/runtime-tags 6.0.164, when dynamic text is interpolated into a <script> or <style> tag the Marko runtime failed to prevent tag breakout when the closing tag used non-lowercase casing. An attacker able to place input inside a <script> or <style> block could break out of the tag with </SCRIPT>, </Style>, etc. and inject arbitrary HTML/JavaScript, resulting in cross-site scripting. This issue has been patched in marko version 5.38.36 and @marko/runtime-tags 6.0.164.

marko 跨站脚本漏洞

marko是marko开源的一个声明式HTML语言，用于构建动态用户界面。 Marko 5.38.36之前版本存在跨站脚本漏洞，该漏洞源于动态文本插入到script或style标签时未阻止非小写闭合标签的逃逸，可能导致跨站脚本攻击。
