Vikunja before 2.7.1 contains a denial of service vulnerability that allows authenticated users to exhaust API process memory by uploading WeKan or vikunja-file imports with no item-count cap. Attackers can submit a ~22 MB WeKan JSON with hundreds of thousands of cards or duplicate IDs to the wekan migrate endpoint, triggering OOM and crashing the instance.
