CVE-2026-108634
MEDIUM 5.3 PoC AVAILABLEJeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to delete department permission bindings via the DELETE /sys/sysDepartPermission/deleteBatch endpoint. Attackers can obtain row ids from the unguarded list endpoint and submit them in the ids parameter to remove menus and buttons departments can grant to their roles.
Public exploit or PoC code exists. Modeled probability is still low, but the barrier to attack is reduced — watch closely.
