CVE-2024-28095Network attack vector

Authenticated cross-user actions via stored News scripts

Published Mar 7, 2024 · Updated Aug 2, 2024

Stored XSS in Schoolbox before 23.1.3 allows remote authenticated users to perform actions in affected users' browser sessions. The published advisory identifies the News functionality as the storage and delivery locus but does not disclose the input field, rendering path, or missing neutralization operation. An authenticated account and a separate user's viewing of the stored News content are required before attacker-controlled script runs in that user's context.
