{"id":"UBUNTU-CVE-2026-24885","details":"Kanboard is project management software focused on Kanban methodology. Prior to 1.2.50, a Cross-Site Request Forgery (CSRF) vulnerability exists in the ProjectPermissionController within the Kanboard application. The application fails to strictly enforce the application/json Content-Type for the changeUserRole action. Although the request body is JSON, the server accepts text/plain, allowing an attacker to craft a malicious form using the text/plain attribute. Which allows unauthorized modification of project user roles if an authenticated admin visits a malicious site This vulnerability is fixed in 1.2.50.","modified":"2026-05-20T16:24:46.680576685Z","published":"2026-02-10T17:16:00Z","upstream":["CVE-2026-24885"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-24885"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-24885"},{"type":"REPORT","url":"https://github.com/kanboard/kanboard/security/advisories/GHSA-582j-h4w4-hwr5"},{"type":"REPORT","url":"https://github.com/kanboard/kanboard/commit/2c56d92783d4a3094812c2f7cba50f80a372f95e"},{"type":"REPORT","url":"https://github.com/kanboard/kanboard/releases/tag/v1.2.50"}],"affected":[{"package":{"name":"kanboard-cli","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/kanboard-cli?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"kanboard-cli","binary_version":"0.0.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.0.1-1","binary_name":"python3-kanboard"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"kanboard-cli","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/kanboard-cli?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"kanboard-cli","binary_version":"0.0.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.0.1-1","binary_name":"python3-kanboard"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"kanboard-cli","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/kanboard-cli?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.2-1.1"],"ecosystem_specific":{"binaries":[{"binary_name":"kanboard-cli","binary_version":"0.0.2-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.1-1.1"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-kanboard","binary_version":"1.0.1-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"kanboard-cli","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/kanboard-cli?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.2-3"],"ecosystem_specific":{"binaries":[{"binary_name":"kanboard-cli","binary_version":"0.0.2-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.1-2","1.1.5-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.5-1","binary_name":"python3-kanboard"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/python-kanboard?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.5-1"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-kanboard","binary_version":"1.1.5-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-24885.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.5-1","1.1.5-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.5-1build1","binary_name":"python3-kanboard"}]},"databa
