Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the hasAccessToLabel function contains a SQL operator precedence bug that allows any authenticated user to read any label that has at least one task association, regardless of project access. Label titles, descriptions, colors, and creator information are exposed. This vulnerability is fixed in 2.3.0.
