{"cve":"CVE-2026-33668","nvd":{"published":"2026-03-24T16:16:34.623","modified":"2026-06-17T10:37:53.677","status":"Analyzed","description":"Vikunja is an open-source self-hosted task management platform. Starting in version 0.18.0 and prior to version 2.2.1, when a user account is disabled or locked, the status check is only enforced on the local login and JWT token refresh paths. Three other authentication paths — API tokens, CalDAV basic auth, and OpenID Connect — do not verify user status, allowing disabled or locked users to continue accessing the API and syncing data. Version 2.2.1 patches the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-285","CWE-863"],"references":["https://github.com/go-vikunja/vikunja/commit/033922309f492996c928122fb49b691339199c35","https://github.com/go-vikunja/vikunja/commit/04704e0fde4b027039cf583110cee7afe136fc1b","https://github.com/go-vikunja/vikunja/commit/0b04768d830c80e9fde1b0962db1499cc652da0e","https://github.com/go-vikunja/vikunja/commit/fd452b9cb6457fd4f9936527a14c359818f1cca7","https://github.com/go-vikunja/vikunja/security/advisories/GHSA-94xm-jj8x-3cr4"],"products":["vikunja:vikunja"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33668","score":0.00461,"percentile":0.39969,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-94xm-jj8x-3cr4","url":"https://osv.dev/vulnerability/GHSA-94xm-jj8x-3cr4","summary":"Vikunja Allows Disabled/Locked User Accounts to Authenticate via API Tokens, CalDAV, and OpenID Connect","modified":"2026-03-26T21:11:25.953771Z","packages":[{"ecosystem":"Go","name":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","ranges":[">=0.18.0 <2.2.1"],"fixed":["2.2.1"]}]},{"id":"GO-2026-4849","url":"https://osv.dev/vulnerability/GO-2026-4849","summary":"Vikunja Allows Disabled/Locked User Accounts to Authenticate via API Tokens, CalDAV, and OpenID Connect in code.vikunja.io/api","modified":"2026-03-26T21:00:50.149141Z","packages":[{"ecosystem":"Go","name":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","ranges":[">=0.18.0"],"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).
