{"id":"CVE-2026-33316","aliases":["GHSA-vq4q-79hh-q767","GO-2026-4798"],"url":"https://o3.security/vulnerability/CVE-2026-33316","summary":"Vikunja’s Improper Access Control Enables Bypass of Administrator-Imposed Account Disablement","details":"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.","published":"2026-03-24T14:59:17.242Z","modified":"2026-08-07T11:48:54.915888407Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"code.vikunja.io/api","fixedVersion":null}],"fix":{"url":"https://github.com/go-vikunja/vikunja/commit/049f4a6be46f9460bd516f489ef9f569574bc70d","label":"go-vikunja/vikunja@049f4a6"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:48:54.915888407Z"}}
