{"id":"CVE-2026-33316","state":"PUBLISHED","title":"Vikunja’s Improper Access Control Enables Bypass of Administrator-Imposed Account Disablement","description":"Vikunja is an open-source self-hosted task management platform. 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.","publishedAt":"2026-03-24T14:59:17.242Z","updatedAt":"2026-03-26T13:08:08.138Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["go-vikunja vikunja"],"affected":[{"vendor":"go-vikunja","product":"vikunja","versions":[{"version":"< 2.2.0","status":"affected"}]}],"references":["https://github.com/go-vikunja/vikunja/security/advisories/GHSA-vq4q-79hh-q767","https://github.com/go-vikunja/vikunja/commit/049f4a6be46f9460bd516f489ef9f569574bc70d","https://github.com/go-vikunja/vikunja/commit/d8570c603da1f26635ce6048d6af85ede827abfb","https://vikunja.io/changelog/vikunja-v2.2.0-was-released"],"weaknesses":["CWE-284","CWE-862","CWE-863"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33316.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33316","state":"PUBLISHED","datePublished":"2026-03-24T14:59:17.242Z","dateUpdated":"2026-03-26T13:08:08.138Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-18T21:23:36.676Z"},"containers":{"cna":{"title":"Vikunja’s Improper Access Control Enables Bypass of Administrator-Imposed Account Disablement","descriptions":[{"lang":"en","value":"Vikunja is an open-source self-hosted task management platform.
