Ellucian Banner Self-Service before the April T2 release (2025-04-23) contains a stored cross-site scripting vulnerability in the course search functionality that allows authenticated Banner ERP users to inject malicious payloads into faculty and course fields by exploiting missing HTML encoding during DOM insertion. Attackers can store malicious JavaScript in fields such as faculty displayName, emailAddress, subjectDescription, or courseTitle through the unauthenticated getFacultyMeetingTimes API endpoint, causing arbitrary script execution.
