What is CVE-2026-109177?

MoguBlog versions up to 6.2 are susceptible to a significant broken access control vulnerability. This flaw permits authenticated administrators to inadvertently manipulate network-disk files belonging to other administrators. By making specially crafted requests to endpoints like /networkDisk/moveFile and batchMoveFile, attackers could bypass crucial admin_uid checks, allowing them to move or rename files and folders of other users without appropriate permissions.

Affected Version(s)

MoguBlog 0 <= 6.2
