Tuleap is vulnerable to XSS attacks when displaying the children of a parent artifact

Tuleap is an Open Source Suite created to facilitate management of software development and collaboration. In Tuleap Community Edition prior to version 16.9.99.1751892857 and Tuleap Enterprise Edition prior to 16.8-5 and 16.9-3, malicious users with some control over certain artifacts could insert malicious code when displaying the children of a parent artifact to force victims to execute the uncontrolled code. This is fixed in version Tuleap Community Edition prior to version 16.9.99.1751892857 and Tuleap Enterprise Edition prior to 16.8-5 and 16.9-3.
