Name of the Vulnerable Software and Affected Versions
Vikunja versions prior to 2.7.1
Description
The Trello, Todoist, and Microsoft To Do migration importers allocate memory without limits. This occurs because remote attachment downloads and API responses are buffered in memory without size caps. An authenticated user can trigger a migration that references oversized API responses or huge attachments served by an attacker, leading to memory exhaustion and crashing the shared API process for all tenants.
Recommendations
Update to version 2.7.1.
