Prior to 2.3.0, the Vikunja file import endpoint uses the attacker-controlled Size field from the JSON metadata inside the import zip instead of the actual decompressed file content length for the file size enforcement check. By setting Size to 0 in the JSON while including large compressed file entries in the zip, an attacker bypasses the configured maximum file size limit. This vulnerability is fixed in 2.3.0."}],"source":{"advisory":"GHSA-qh78-rvg3-cv54","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-qh78-rvg3-cv54","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-14T14:19:25.945976Z","id":"CVE-2026-35602","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-14T14:19:30.140Z"}}]}}
