CVE-2026-89328

FluentBoards < 2.0.15 - Board Member+ Board Membership and Public Access Modification

The FluentBoards WordPress plugin before 2.0.15 does not properly verify that a user holds board-manager privileges before performing several board-management operations, checking only board membership. This allows any member of a board to carry out manager-only actions on it, including adding or removing members and enabling public access to a private board.
