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.","state":2,"publishedAt":"2026-09-15T18:32:30+00:00","modifiedAt":"2026-10-09T21:00:05.5258733+00:00","affected":[{"ecosystem":"Go","name":"code.vikunja.io/api","ranges":[],"versions":["2.5.0"],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/go-vikunja/vikunja/security/advisories/GHSA-pqf9-h8g4-8gmh","https://nvd.nist.gov/vuln/detail/CVE-2026-91969","https://www.vulncheck.com/advisories/vikunja-before-2.6.0-resource-exhaustion-via-csv-migration"],"sourceUrl":"https://github.com/advisories/GHSA-55p4-8j34-jv53","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-55p4-8j34-jv53","identifiers":["GHSA-55p4-8j34-jv53"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
