在 1.6.20 之前的 Roundcube Webmail 以及 1.7.x 系列中 1.7.5 之前的版本，受 HTML 消息中 CSS 作用域绕过漏洞的影响。rcube_utils::mod_css_styles() 函数未将诸如 "@layer a;" 这样的 @ 规则前导部分（at-rule prologue）视为选择器边界，同时也未能正确处理以 "::" 开头的选择器。因此，位于 @ 规则之后的选择器未被限制在消息正文的作用域内，而是被应用到了整个 Roundcube 界面。攻击者可利用此漏洞，通过 H

Vulnerability Description
Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a CSS scoping bypass in HTML messages. rcube_utils::mod_css_styles() did not treat an at-rule prologue such as @layer a; as a selector boundary, and did not handle selectors beginning with ::, so selectors following an at-rule were left unscoped and applied to the whole Roundcube interface instead of being confined to the message body. This allows an HTML message to restyle application chrome for UI redressing and spoofing. Upstream fixed this in the commit “Fix CSS scoping bypass in HTML messages using at-rules”.
