CVE-2026-48848 Details
Description
Roundcube Webmail 1.6.x before 1.6.16 and 1.7.x before 1.7 has insufficient HTML sanitization that could lead to Cascading Style Sheets (CSS) injection via an SVG document that has an animate element with the attributeName attribute.
A vulnerability exists in Roundcube Webmail versions 1.6.x prior to 1.6.16 and 1.7.x prior to 1.7, due to inadequate HTML sanitization. This flaw could enable Cascading Style Sheets (CSS) injection through an SVG document containing an animate element with the attributeName attribute. The issue arises because the HTML sanitizer fails to properly handle certain SVG animations, allowing malicious users to inject harmful styles that could be executed when the SVG is rendered.
Users are advised to update to Roundcube Webmail versions 1.6.16 or 1.7.1, both of which include the necessary fix. Instructions for downloading these versions are available on the Roundcube GitHub release pages.
