JeecgBoot through 3.9.5 Missing Authorization via sysMessageTemplate/add Endpoint

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to create message templates by calling POST /sys/message/sysMessageTemplate/add. Attackers holding only minimal roles can insert arbitrary notification templates with chosen codes and content into the shared sys_sms_template library used for system, e-mail, SMS and IM notifications.
