{"id":"CVE-2026-33675","state":"PUBLISHED","title":"Vikunja has SSRF via Todoist/Trello Migration File Attachment URLs that Allows Reading Internal Network Resources","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.","publishedAt":"2026-03-24T15:33:05.868Z","updatedAt":"2026-03-24T18:15:30.530Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["go-vikunja vikunja"],"affected":[{"vendor":"go-vikunja","product":"vikunja","versions":[{"version":"< 2.2.1","status":"affected"}]}],"references":["https://github.com/go-vikunja/vikunja/security/advisories/GHSA-g66v-54v9-52pr","https://github.com/go-vikunja/vikunja/commit/93297742236e3d33af72c993e5da960db01d259e","https://vikunja.io/changelog/vikunja-v2.2.2-was-released"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33675.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33675","state":"PUBLISHED","datePublished":"2026-03-24T15:33:05.868Z","dateUpdated":"2026-03-24T18:15:30.530Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-23T16:34:59.930Z"},"containers":{"cna":{"title":"Vikunja has SSRF via Todoist/Trello Migration File Attachment URLs that Allows Reading Internal Network Resources","descriptions":[{"lang":"en","value":"Vikunja is an open-source self-hosted task management platform.
