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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","score":5.4},"cwes":["CWE-863"],"references":["https://github.com/go-vikunja/vikunja/security/advisories/GHSA-564f-wx8x-878h","https://vikunja.io/changelog/vikunja-v2.2.0-was-released"],"products":["vikunja:vikunja"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33312","score":0.00219,"percentile":0.12484,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-564f-wx8x-878h","url":"https://osv.dev/vulnerability/GHSA-564f-wx8x-878h","summary":"Vikunja read-only users can delete project background images via broken object-level authorization","modified":"2026-03-23T18:56:15.961357Z","packages":[{"ecosystem":"Go","name":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","ranges":[">=0.20.2 <2.2.0"],"fixed":["2.2.0"]}]},{"id":"GO-2026-4795","url":"https://osv.dev/vulnerability/GO-2026-4795","summary":"Vikunja read-only users can delete project background images via broken object-level authorization in code.vikunja.io/api","modified":"2026-03-23T18:45:21.141847Z","packages":[{"ecosystem":"Go","name":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","ranges":[">=0.20.2"],"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).
