CVE-2026-123509

Vikunja before 2.7.1 contains an uncontrolled resource consumption vulnerability that allows project writers or view admins to create unlimited kanban buckets due to missing count caps. Attackers can create thousands of buckets so every kanban read runs a task SELECT and COUNT per bucket, generating heavy database load.
