CVE-2022-46160 is an authorization vulnerability affecting Enalean's Tuleap, an open-source software suite designed to facilitate software development management and team collaboration. The flaw exists in versions prior to 14.2.99.104, where project-level authorization checks are improperly enforced when users access the project homepage and associated dashboards. Specifically, unauthorized users can view certain information exposed by dashboard widgets, such as the number of project members and the content of the Notes widget, despite lacking proper permissions to access the project. This incorrect authorization (CWE-863) does not allow full project access but leaks potentially sensitive metadata and notes that could aid in reconnaissance or social engineering. The vulnerability has been addressed in Tuleap Community Edition 14.2.99.104 and Enterprise Editions 14.2-4 and 14.1-5. No known exploits have been reported in the wild, and the issue primarily affects the confidentiality of project information rather than integrity or availability. The flaw arises from insufficient access control validation on the project homepage widgets, allowing unauthorized data exposure without requiring authentication beyond what is needed to access the dashboard interface. This vulnerability highlights the importance of strict authorization checks in collaborative platforms where project data confidentiality is critical.

For European organizations using Tuleap, especially those managing sensitive or proprietary software development projects, this vulnerability could lead to unauthorized disclosure of project membership and notes. While it does not grant full project access or code exposure, the leaked information could facilitate targeted social engineering attacks, insider threat identification, or competitive intelligence gathering. Organizations in regulated industries such as finance, healthcare, or critical infrastructure may face compliance risks if sensitive project details are inadvertently exposed. The impact is primarily on confidentiality, with limited direct effect on system integrity or availability. However, the information leakage could be leveraged as a stepping stone for more sophisticated attacks. Given Tuleap's role in managing development workflows, unauthorized insight into project structures and notes could undermine trust and collaboration security within affected teams.

Organizations should promptly upgrade all Tuleap instances to the patched versions: Community Edition 14.2.99.104 or Enterprise Editions 14.2-4 and 14.1-5. Until upgrades are applied, administrators should restrict access to project dashboards to trusted users only, potentially by implementing network-level access controls or VPN requirements. Review and tighten project-level permissions to ensure minimal exposure of sensitive widgets or notes. Additionally, audit existing project notes and membership lists for sensitive information that could be exploited if leaked. Implement monitoring to detect unusual access patterns to project dashboards. Consider disabling or customizing widgets that expose sensitive data until the patch is applied. Finally, educate users about the potential risks of information leakage through collaboration tools and encourage cautious sharing of sensitive notes within projects.
