{"id":"CVE-2026-33668","aliases":["GHSA-94xm-jj8x-3cr4","GO-2026-4849"],"url":"https://o3.security/vulnerability/CVE-2026-33668","summary":"Vikunja Allows Disabled/Locked User Accounts to Authenticate via API Tokens, CalDAV, and OpenID Connect","details":"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.","published":"2026-03-24T15:30:27.159Z","modified":"2026-08-12T03:51:44.692701591Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"code.vikunja.io/api","fixedVersion":"2.2.1"}],"fix":{"url":"https://github.com/go-vikunja/vikunja/commit/033922309f492996c928122fb49b691339199c35","label":"go-vikunja/vikunja@0339223"},"references":[{"type":"WEB","url":"https://vikunja.io/changelog/vikunja-v2.2.2-was-released"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33668.json"},{"type":"ADVISORY","url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-94xm-jj8x-3cr4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33668"},{"type":"FIX","url":"https://github.com/go-vikunja/vikunja/commit/033922309f492996c928122fb49b691339199c35"},{"type":"FIX","url":"https://github.com/go-vikunja/vikunja/commit/04704e0fde4b027039cf583110cee7afe136fc1b"},{"type":"FIX","url":"https://github.com/go-vikunja/vikunja/commit/0b04768d830c80e9fde1b0962db1499cc652da0e"},{"type":"FIX","url":"https://github.com/go-vikunja/vikunja/commit/fd452b9cb6457fd4f9936527a14c359818f1cca7"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:44.692701591Z"}}
