CVE-2026-47106Network attack vector

Stored XSS via unsanitized course metadata

Published Jun 9, 2026 · Updated Jun 9, 2026

Stored XSS in Ellucian Banner Self-Service before April T2 allows remote authenticated users to run scripts in course viewers' browsers. The getFacultyMeetingTimes API returns attacker-controlled faculty and course fields, and the course-search page inserts them into the DOM without HTML encoding. Banner ERP write access is required to store the payload, and execution occurs when another user views the course's meeting times.
