This link is maintained to preserve external references.\n\n### Original Description\nvikunja versions before 2.6.0 contain a resource exhaustion vulnerability in the POST /api/v2/migration/csv/migrate endpoint that fails to limit parsed row cardinality. Authenticated attackers can upload multipart CSV files with millions of tiny records to exhaust process memory and terminate the API service.\n\n## Affected packages\n\n- `code.vikunja.io/api = 2.5.0`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"twilight","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
