{"id":"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.","aliases":["GHSA-94xm-jj8x-3cr4","GO-2026-4849"],"modified":"2026-04-10T05:42:53.703384Z","published":"2026-03-24T15:30:27.159Z","related":["SUSE-SU-2026:1135-1"],"database_specific":{"cwe_ids":["CWE-285","CWE-863"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33668.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33668.json"},{"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"},{"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":"WEB","url":"https://vikunja.io/changelog/vikunja-v2.2.2-was-released"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-vikunja/vikunja","events":[{"introduced":"24bb7e98fad57aea311bcd06e88ac318b69ea923"},{"fixed":"6d5d3e051f4f9f6d72f5d1d552c2d90910fccb28"}],"database_specific":{"versions":[{"introduced":"0.18.0"},{"fixed":"2.2.1"}]}}],"versions":["v0.18.0","v0.18.1","v0.19.0","v0.19.1","v0.19.2","v0.20.0","v0.20.1","v0.20.3","v0.20.4","v0.21.0","v0.22.0","v0.22.1","v0.23.0","v0.24.1","v1.0.0","v1.0.0-rc0","v1.0.0-rc1","v1.0.0-rc2","v1.0.0-rc3","v1.0.0-rc4","v1.1.0","v2.0.0","v2.1.0","v2.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33668.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
