Vikunja from 1.0.0 before 2.7.1 contains an uncontrolled resource consumption vulnerability that allows authenticated users to bypass service.maxitemsperpage by sending page=0 to /api/v1 list endpoints. Attackers can self-register and repeatedly request page=0 to force unbounded SQL queries, memory materialisation, and per-row query fan-out, degrading availability for other users.
