CVE-2026-35596 Details
Description
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.
A vulnerability in Vikunja's task management platform prior to version 2.3.0 allows any authenticated user to access labels associated with tasks, regardless of project permissions. This issue stems from a SQL operator precedence error in the 'hasAccessToLabel' function, which improperly groups query conditions. As a result, labels with task associations can be accessed without the necessary project rights, leading to unauthorized exposure of label details such as titles, descriptions, colors, and creator information.
Users can update to Vikunja version 2.3.0, where this vulnerability has been fixed.
