FluentBoards WordPress plugin vulnerabilities

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.

The FluentBoards WordPress plugin before 2.0.15 does not verify that a board member submitting a comment is the user the comment is attributed to, allowing any board member to post comments that appear to be authored by another user, including administrators.

The FluentBoards WordPress plugin before version 1.95.3 does not verify that the items selected for a board import operation belong to a board the requesting user is authorized to access. This allows any authenticated user with member access to a single board to copy and read the stages and tasks (including titles, descriptions and file attachments) of any other board on the site.
