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.

Affected: Ubuntu:18.04:LTS: kanboard-cli, Ubuntu:18.04:LTS: python-kanboard, Ubuntu:20.04:LTS: kanboard-cli, Ubuntu:20.04:LTS: python-kanboard, Ubuntu:22.04:LTS: kanboard-cli, Ubuntu:22.04:LTS: python-kanboard, Ubuntu:24.04:LTS: kanboard-cli, Ubuntu:24.04:LTS: python-kanboard, Ubuntu:25.10: python-kanboard, Ubuntu:26.04:LTS: python-kanboard
