CVE-2026-33350Network attack vector

Unauthenticated data disclosure via interpolated MRI identifiers

Published Apr 8, 2026 · Updated Apr 8, 2026

SQL injection in LORIS before 27.0.3 and in 28.0.0 allows remote attackers to read server data through MRI feedback requests. FeedbackMRI::_buildWhere inserts the FileID or SessionID value directly into the feedback_mri_comments SELECT instead of binding it as a parameter. No authentication or user interaction is required, and the affected query exposes database records without modifying them.
