CVE-2026-7677 Details
Description
A vulnerability was determined in kerwincui FastBee up to 1.2.1. The impacted element is the function Add of the file springboot/fastbee-admin/src/main/java/com/fastbee/web/controller/system/SysNoticeController.java of the component System Notice Handler. This manipulation of the argument noticeContent causes cross site scripting. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
A stored cross-site scripting vulnerability has been identified in kerwincui FastBee versions through 1.2.1. The issue resides in the System Notice Handler, specifically within the Add function of the SysNoticeController.java file. The vulnerability arises because the application treats the noticeContent argument as trusted HTML, storing it directly in the backend. When rendered on the frontend using v-html, this bypasses Vue's default escaping, executing attacker-controlled markup and creating a full stored XSS chain. The vulnerability can be exploited remotely by users with system:notice:add or system:notice:edit permissions.
