CVE-2026-108868: JeecgBoot missing authorization in system announcement publishing

CVE-2026-108868 · Severity: medium · CVSS 4.3 · Published 2026-10-11

JeecgBoot is a low-code application development framework. This vulnerability allows any authenticated user to publish system announcements to arbitrary recipients through multiple notification channels (WebSocket, DingTalk, WeCom, Feishu, UniPush) by forging the sender identity. An attacker with basic system access can impersonate administrators and send unauthorized notifications to any user, potentially spreading misinformation or triggering phishing attacks.

Technologies: JeecgBoot. Vendors: JeecgBoot.

Technical details

The POST /sys/api/sendBusTemplateAnnouncement endpoint in JeecgBoot lacks proper authorization checks, allowing authenticated users to supply arbitrary templateCode, toUser, and fromUser parameters. The vulnerability permits low-privileged attackers to send notifications across multiple channels with a spoofed sender identity. An authorization bypass rather than authentication bypass; exploitation requires valid credentials but no admin role.
