CVE-2026-25924 | Kanboard is Missing Access Control on Plugin Installation leading to Administrative RCE

Exp

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.

8.4 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
