{"id":"UBUNTU-CVE-2026-25924","details":"Kanboard is project management software focused on Kanban methodology. Prior to 1.2.50, a security control bypass vulnerability in Kanboard allows an authenticated administrator to achieve full Remote Code Execution (RCE). Although the application correctly hides the plugin installation interface when the PLUGIN_INSTALLER configuration is set to false, the underlying backend endpoint fails to verify this security setting. An attacker can exploit this oversight to force the server to download and install a malicious plugin, leading to arbitrary code execution. This vulnerability is fixed in 1.2.50.","modified":"2026-02-18T17:32:15Z","published":"2026-02-11T21:16:00Z","upstream":["CVE-2026-25924"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-25924"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-25924"},{"type":"REPORT","url":"https://github.com/kanboard/kanboard/security/advisories/GHSA-grch-p7vf-vc4f"},{"type":"REPORT","url":"https://github.com/kanboard/kanboard/commit/b9ada89b1a64034612fc4262b88c42458c0d6ee4"},{"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@0.0.2-1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.2-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0.2-1","binary_name":"kanboard-cli"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-25924.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard@1.0.1-1?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-2026-25924.json"}},{"package":{"name":"kanboard-cli","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/kanboard-cli@0.0.2-1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.2-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0.2-1","binary_name":"kanboard-cli"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-25924.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard@1.0.1-1?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-2026-25924.json"}},{"package":{"name":"kanboard-cli","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/kanboard-cli@0.0.2-1.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.2-1.1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0.2-1.1","binary_name":"kanboard-cli"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-25924.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard@1.0.1-1.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.1-1.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.0.1-1.1","binary_name":"python3-kanboard"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-25924.json"}},{"package":{"name":"kanboard-cli","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/kanboard-cli@0.0.2-3?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.2-3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0.2-3","binary_name":"kanboard-cli"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-25924.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/python-kanboard@1.1.5-1?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-2026-25924.json"}},{"package":{"name":"python-kanboard","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/python-kanboard@1.1.5-1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["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-2026-25924.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
