CVE-2026-123507 Details
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.
A nil pointer dereference vulnerability has been identified in Vikunja versions 0.24.0 prior to 2.7.1. This vulnerability allows project admins to disrupt project views by saving a filter-mode bucket configuration with a null filter. The issue arises because the 'validateProjectViewFilters' function ignores nil entries, causing subsequent reads of the view to panic in the kanban and task collection code. This results in an HTTP 500 error for all project members.
Users can update to Vikunja version 2.7.1 or later, where this vulnerability has been patched.
