Senserva AI Opinion for CVE-2025-68461

A crafted SVG using the animate tag is enough to execute script in a Roundcube Webmail user's session, a cross-site scripting flaw rated Medium Severity at CVSS 6.1 with a 20% EPSS score, confirmed exploited since 2026-02-20. Paired with the Roundcube deserialization bug added to the KEV catalog the same day, it gives attackers a mail-delivered entry point that can escalate to code execution. A victim only has to open the message.

Do this: Patch Roundcube together with its companion February flaw and consider stripping SVG content from inbound mail.
