CVE-2026-7677Public exploitNetwork attack vector

Stored script execution via unsanitized notice content

Published May 3, 2026 · Updated May 3, 2026

Stored cross-site scripting in FastBee 1.2.0 through 1.2.1 allows remote authenticated users to inject script through noticeContent. The Add function in SysNoticeController stores noticeContent without neutralizing active HTML before notice views render it in a browser. Low-privilege access and a user viewing the crafted notice are required, enabling unauthorized actions in that user's web session.
