Official description
Vikunja before 2.7.1 contains a resource exhaustion vulnerability in the vikunja-file ZIP importer that allows authenticated users to consume CPU and memory by uploading archives with excessive entries. Attackers can upload export ZIPs containing many empty or non-files/ entries that bypass the per-entry caps, forcing scanArchive to process every entry twice.
