RoundCube 1.7.1 patches multiple pre‑authentication security flaws including XSS, CSS injection via SVG, SQL injection in the virtuser_query plugin, SSRF bypasses, remote image rendering bypass, and arbitrary file deletion through session poisoning.

Why it matters: All seven critical vulnerabilities affect core services; upgrade to version 1.7.1 immediately to mitigate pre‑auth code execution and data leakage risks.
