CVE-2026-35599 Vikunja has an Algorithmic Complexity DoS in Repeating Task Handler

Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the addRepeatIntervalToTime function uses an On loop that advances a date by the task's RepeatAfter duration until it exceeds the current time. By creating a repeating task with a 1-second interval and a due date far ...
