Security readout for executives and security teams

CVE-2021-27330 is a cross-site scripting issue in Triconsole Datepicker Calendar before 3.77. If exposed, an attacker could run script in a user's browser and potentially access still-active authentication cookies, enabling follow-on abuse. The source bundle does not provide CVSS scoring or confirmed active exploitation. Exposure is most likely where legacy Triconsole Datepicker Calendar code is deployed on public or authenticated web applications, especially if calendar_form.php is reachable and sessions use cookies that remain active after login. Treat this as a targeted legacy-web risk. Prioritize remediation if the component is internet-facing, used in authenticated workflows, or handles privileged sessions. Lower urgency if the component is absent or unreachable. Mitigation focus: Inventory applications using Triconsole Datepicker Calendar and identify versions before 3.77.; Check vendor guidance and update to a non-affected version if available.; Remove or disable unused Triconsole calendar code, especially calendar_form.php..
