Prior to version 2.2.0, a flaw in Vikunja’s password reset logic allows disabled users to regain access to their accounts. The `ResetPassword()` function sets the user’s status to `StatusActive` after a successful password reset without verifying whether the account was previously disabled. By requesting a reset token through `/api/v1/user/password/token` and completing the reset via `/api/v1/user/password/reset`, a disabled user can reactivate their account and bypass administrator-imposed account disablement. Version 2.2.0 patches the issue.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-vikunja/vikunja","events":[{"introduced":"0"},{"fixed":"b365be1881641dd2791d3dff4c26ad941c13cef6"},{"fixed":"049f4a6be46f9460bd516f489ef9f569574bc70d"},{"fixed":"d8570c603da1f26635ce6048d6af85ede827abfb"}],"database_specific":{"cpe":"cpe:2.3:a:vikunja:vikunja:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.2.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v2.1.0","v2.0.0","v1.1.0","v1.0.0","v1.0.0-rc4","v1.0.0-rc3","v1.0.0-rc2","v1.0.0-rc1","v1.0.0-rc0","v0.24.1","v0.23.0","v0.22.1","v0.22.0","v0.21.0","v0.20.4","v0.20.3","v0.20.1","v0.20.0","v0.19.2","v0.19.1","v0.19.0","v0.18.1","v0.18.0","v0.17.0","v0.16.0","v0.15.0","v0.14.0","v0.13","v0.12","v0.11","v0.10","v0.9","v0.8","v0.7","v0.6","v0.5","v0.4","v0.3","v0.2","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33316.json"}}],"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-2026-33316.json"},{"type":"ADVISORY","url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-vq4q-79hh-q767"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33316"},{"type":"FIX","url":"https://github.com/go-vikunja/vikunja/commit/049f4a6be46f9460bd516f489ef9f569574bc70d"},{"type":"FIX","url":"https://github.com/go-vikunja/vikunja/commit/d8570c603da1f26635ce6048d6af85ede827abfb"}],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-284","CWE-862","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33316.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
