{"id":"CVE-2026-29056","summary":"Kanboard's privilege escalation via mass assignment in user invite registration allows any invited user to become admin","details":"Kanboard is project management software focused on Kanban methodology. Prior to 1.2.51, Kanboard's user invite registration endpoint (`UserInviteController::register()`) accepts all POST parameters and passes them to `UserModel::create()` without filtering out the `role` field. An attacker who receives an invite link can inject `role=app-admin` in the registration form to create an administrator account. Version 1.2.51 fixes the issue.","aliases":["GHSA-2jvj-q44v-6p3x"],"modified":"2026-04-10T05:41:30.653120Z","published":"2026-03-18T01:56:19.315Z","database_specific":{"cwe_ids":["CWE-915"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29056.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29056.json"},{"type":"ADVISORY","url":"https://github.com/kanboard/kanboard/security/advisories/GHSA-2jvj-q44v-6p3x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29056"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kanboard/kanboard","events":[{"introduced":"0"},{"fixed":"1c27f48cc2ef2bfbf6097c5ec19e61d1aa60dba6"}]}],"versions":["v1.0.0","v1.0.1","v1.0.10","v1.0.11","v1.0.12","v1.0.13","v1.0.14","v1.0.15","v1.0.16","v1.0.17","v1.0.18","v1.0.19","v1.0.2","v1.0.20","v1.0.26","v1.0.27","v1.0.28","v1.0.29","v1.0.3","v1.0.30","v1.0.31","v1.0.32","v1.0.33","v1.0.34","v1.0.35","v1.0.36","v1.0.37","v1.0.38","v1.0.39","v1.0.4","v1.0.40","v1.0.41","v1.0.42","v1.0.43","v1.0.44","v1.0.45","v1.0.46","v1.0.48","v1.0.5","v1.0.6","v1.0.7","v1.0.8","v1.0.9","v1.1.0","v1.1.1","v1.2.0","v1.2.1","v1.2.10","v1.2.11","v1.2.12","v1.2.13","v1.2.14","v1.2.15","v1.2.16","v1.2.17","v1.2.18","v1.2.19","v1.2.2","v1.2.20","v1.2.21","v1.2.22","v1.2.23","v1.2.24","v1.2.25","v1.2.26","v1.2.27","v1.2.28","v1.2.29","v1.2.3","v1.2.30","v1.2.31","v1.2.32","v1.2.33","v1.2.34","v1.2.35","v1.2.36","v1.2.37","v1.2.38","v1.2.39","v1.2.4","v1.2.40","v1.2.41","v1.2.42","v1.2.43","v1.2.44","v1.2.45","v1.2.46","v1.2.47","v1.2.49","v1.2.5","v1.2.50","v1.2.6","v1.2.7","v1.2.8","v1.2.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-29056.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:H/SI:N/SA:N/E:P"}]}
