{"cve":"CVE-2026-33675","nvd":{"published":"2026-03-24T16:16:34.787","modified":"2026-06-17T10:37:54.450","status":"Analyzed","description":"Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the migration helper functions `DownloadFile` and `DownloadFileWithHeaders` in `pkg/modules/migration/helpers.go` make arbitrary HTTP GET requests without any SSRF protection. When a user triggers a Todoist or Trello migration, file attachment URLs from the third-party API response are passed directly to these functions, allowing an attacker to force the Vikunja server to fetch internal network resources and return the response as a downloadable task attachment. Version 2.2.1 patches the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L","score":5.4},"cwes":["CWE-918"],"references":["https://github.com/go-vikunja/vikunja/commit/93297742236e3d33af72c993e5da960db01d259e","https://github.com/go-vikunja/vikunja/security/advisories/GHSA-g66v-54v9-52pr","https://vikunja.io/changelog/vikunja-v2.2.2-was-released","https://github.com/go-vikunja/vikunja/security/advisories/GHSA-g66v-54v9-52pr"],"products":["vikunja:vikunja"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33675","score":0.00277,"percentile":0.20169,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-g66v-54v9-52pr","url":"https://osv.dev/vulnerability/GHSA-g66v-54v9-52pr","summary":"Vikunja has SSRF via Todoist/Trello Migration File Attachment URLs that Allows Reading Internal Network Resources","modified":"2026-03-26T21:11:08.627022Z","packages":[{"ecosystem":"Go","name":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","ranges":["<2.2.1"],"fixed":["2.2.1"]}]},{"id":"GO-2026-4851","url":"https://osv.dev/vulnerability/GO-2026-4851","summary":"Vikunja has SSRF via Todoist/Trello Migration File Attachment URLs that Allows Reading Internal Network Resources in code.vikunja.io/api","modified":"2026-03-26T21:04:19.333703Z","packages":[{"ecosystem":"Go","name":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
