CVE-2026-108662
JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to remove users from tenant product packs via PUT /sys/tenant/deleteTenantPackUser.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
Description
JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to remove users from tenant product packs via PUT /sys/tenant/deleteTenantPackUser. Attackers can supply arbitrary userId and packId values in the request body to remove any user from any tenant's product pack, revoking permissions such as tenant administrator access.
