  • Detect SVG documents containing the <animate> tag delivered via email (as attachment or inline content) to Roundcube Webmail users — this is the specific attack vector for CVE-2025-68461 XSS exploitation.
  • Flag Roundcube Webmail instances running versions prior to 1.5.12 or prior to 1.6.12 as vulnerable; over 46,000 Roundcube instances are internet-accessible per Shodan.
  • Monitor Roundcube webmail sessions for signs of session hijacking or credential theft following delivery of SVG-containing emails, as successful exploitation enables script execution in the victim's authenticated session.
  • Inspect inbound email content and attachments for SVG documents embedding <animate> tags; the attack requires no authentication and is low-complexity, requiring only that the victim opens or views the malicious email.
  • ·Exploitation requires user interaction — the victim must open an email containing a malicious SVG attachment or view inline SVG content; this limits but does not eliminate the attack surface.
  • ·CISA KEV remediation deadline for FCEB agencies is 2026-03-13; patch to Roundcube 1.6.12 or 1.5.12 (or Debian/Ubuntu distro-specific backport versions) to remediate.
