Security readout for executives and security teams
CVE-2016-4552 is a stored cross-site scripting issue in Roundcube Webmail before 1.2.0. A crafted email could cause script or HTML injection when rendered by a vulnerable webmail user. The business risk is account/session exposure inside webmail, especially for organizations still running legacy Roundcube deployments. Exposure is likely limited to Roundcube Webmail deployments older than 1.2.0, particularly internet-accessible webmail used to view untrusted email. Organizations using vendor-packaged Roundcube should verify whether their distribution backported the fix. Treat this as a moderate-priority legacy webmail risk. It is not listed as known exploited in the provided sources, but vulnerable systems process untrusted email and may expose sensitive mailbox sessions. Fix or retire old Roundcube quickly if still present. Mitigation focus: Upgrade Roundcube Webmail to 1.2.0 or a later supported release.; Apply fixed vendor packages where Roundcube is managed by a Linux distribution.; Prioritize externally exposed webmail and high-value mailbox environments..
