CVE-2026-47106 Ellucian CVE debrief

CVE-2026-47106 is a stored cross-site scripting (XSS) vulnerability in Ellucian Banner Self-Service before the April T2 release (2025-04-23). The vulnerability allows authenticated Banner ERP users to inject malicious payloads into faculty and course fields by exploiting missing HTML encoding during DOM insertion. An attacker with Banner ERP write access can store malicious JavaScript in fields such as faculty displayName, emailAddress, subjectDescription, or courseTitle; these values are subsequently served unsanitized by the unauthenticated getFacultyMeetingTimes API endpoint, causing arbitrary script execution in the browser of any user who views the affected course's meeting times.
