CVE-2025-65962 identifies a Cross-Site Request Forgery (CSRF) vulnerability in Enalean's Tuleap software, a widely used open-source suite for software development management and collaboration. The vulnerability exists in versions prior to 17.0.99.1763803709 for the Community Edition and versions prior to 17.0-4 and 16.13-9 for the Enterprise Editions. The root cause is the absence of proper CSRF protections in the tracker field dependencies component, which allows an attacker to craft malicious requests that, when executed by an authenticated user, can modify tracker fields without the user's explicit consent. Exploitation requires the attacker to have at least limited privileges (PR:L) and user interaction (UI:R), such as convincing a user to click a malicious link or visit a crafted webpage. The CVSS 3.1 base score is 4.6, reflecting a medium severity level due to the limited impact on confidentiality (none), but with potential integrity and availability impacts through unauthorized data modification. The vulnerability does not require elevated privileges beyond limited user rights, but it does require the victim to be authenticated and interact with the attack vector. No public exploits have been reported to date. The vulnerability is mitigated by upgrading to the patched versions specified by Enalean. This flaw could be leveraged to disrupt project tracking data, potentially impacting project management workflows and data reliability within affected organizations.

For European organizations, the impact of CVE-2025-65962 primarily concerns the integrity and availability of project tracking data within Tuleap instances. Unauthorized modification of tracker fields could lead to corrupted project data, mismanagement of tasks, and disruption of software development processes. This can result in delays, reduced productivity, and potential compliance issues if project data integrity is critical for audits or regulatory requirements. While confidentiality is not directly impacted, the alteration of project data could indirectly affect decision-making and operational security. Organizations relying heavily on Tuleap for critical software development, especially in regulated industries such as finance, healthcare, or government sectors, may face operational risks. The requirement for user interaction and limited privileges reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks, especially social engineering campaigns aimed at authenticated users.

The primary mitigation is to upgrade all affected Tuleap instances to the fixed versions: Community Edition 17.0.99.1763803709 or later, and Enterprise Editions 17.0-4 or 16.13-9 or later. Beyond patching, organizations should implement strict CSRF protections by verifying anti-CSRF tokens on all state-changing requests, particularly in tracker field dependencies. Enforce the principle of least privilege by limiting user permissions to only those necessary for their roles, reducing the potential impact of compromised accounts. Educate users about the risks of social engineering and phishing attacks that could trigger CSRF exploits. Employ web application firewalls (WAFs) with rules to detect and block suspicious CSRF attempts. Regularly audit and monitor Tuleap logs for unusual modifications to tracker fields or unexpected user activities. Finally, consider network segmentation and access controls to limit exposure of Tuleap instances to only trusted users and networks.
