Starting in version 0.20.2 and prior to version 2.2.0, the `DELETE /api/v1/projects/:project/background` endpoint checks `CanRead` permission instead of `CanUpdate`, allowing any user with read-only access to a project to permanently delete its background image. Version 2.2.0 fixes the issue.","published":"2026-03-20T14:42:14.137Z","modified":"2026-08-07T11:31:27.593810976Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"code.vikunja.io/api","fixedVersion":"2.2.0"}],"fix":null,"references":[{"type":"WEB","url":"https://vikunja.io/changelog/vikunja-v2.2.0-was-released"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33312.json"},{"type":"ADVISORY","url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-564f-wx8x-878h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33312"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:27.593810976Z"}}
