What is CVE-2026-25924?
CVE-2026-25924 is a high-severity missing authorization vulnerability in kanboard, published on 11 Feb 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official description
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.
