Tuleap is a free and open source suite to improve management of software development and collaboration. Prior to version 14.10.99.4 of Tuleap Community Edition and prior to versions 14.10-2 and 14.9-5 of Tuleap Enterprise Edition, content displayed in the "card fields" (visible in the kanban and PV2 apps) is not properly escaped. A malicious user with the capability to create an artifact or to edit a field used as a card field could force victim to execute uncontrolled code. Tuleap Community Edition 14.10.99.4, Tuleap Enterprise Edition 14.10-2, and Tuleap Enterprise Edition 14.9-5 contain a fix.
