Description
Vikunja from 0.24.0 before 2.7.1 contains a nil pointer dereference vulnerability that allows project admins to break project views by saving a filter-mode bucket configuration with a null filter. Because validateProjectViewFilters skips nil entries, every subsequent read of the view panics in kanban and task collection code, returning HTTP 500 to all project members.
