CVE-2025-64498 is a Cross-Site Request Forgery (CSRF) vulnerability identified in Enalean's Tuleap software, an open-source suite widely used for software development management and collaboration. The vulnerability exists in Tuleap Community Edition versions below 17.0.99.1762444754 and Enterprise Edition versions prior to 17.0-2, 16.13-7, and 16.12-10. The flaw allows an attacker to trick authenticated users into unknowingly submitting crafted HTTP requests that change tracker general settings within the Tuleap platform. Since the vulnerability exploits the trust a web application places in the user's browser, it requires the victim to be authenticated and to interact with a maliciously crafted link or webpage. The vulnerability impacts the integrity and availability of the system by enabling unauthorized changes to configuration settings, which could disrupt project tracking and management workflows. The CVSS v3.1 base score is 4.6, indicating medium severity, with attack vector as network, low attack complexity, requiring privileges and user interaction, and impacting integrity and availability but not confidentiality. No known exploits have been reported in the wild, but the vulnerability poses a risk to organizations relying on Tuleap for critical development processes. The issue is fixed in the specified patched versions, and users are advised to upgrade promptly. Additional mitigations include implementing anti-CSRF tokens and monitoring for anomalous configuration changes.

For European organizations, especially those in software development, IT services, and collaborative project management, this vulnerability could lead to unauthorized modification of tracker settings, potentially disrupting workflows, causing mismanagement of development tasks, and impacting project delivery timelines. While it does not expose sensitive data directly, the integrity and availability of project management data are at risk, which can indirectly affect confidentiality if misconfigurations lead to data leaks. Organizations using vulnerable versions of Tuleap may face operational disruptions and increased risk of insider threats or targeted attacks leveraging this CSRF flaw. The requirement for user interaction and authentication limits the attack surface but does not eliminate risk, particularly in environments with high user activity and external exposure. The absence of known exploits suggests a window for proactive mitigation before exploitation occurs.

1. Upgrade all Tuleap installations to the fixed versions: Community Edition 17.0.99.1762444754 or Enterprise Edition 17.0-2, 16.13-7, or 16.12-10 as applicable. 2. Implement and enforce anti-CSRF tokens in all web forms and state-changing requests if not already present. 3. Conduct user awareness training to recognize and avoid phishing or malicious links that could trigger CSRF attacks. 4. Restrict access to Tuleap interfaces to trusted networks or VPNs to reduce exposure. 5. Monitor logs for unusual changes in tracker settings or configuration modifications that could indicate exploitation attempts. 6. Employ web application firewalls (WAFs) with rules to detect and block CSRF attack patterns. 7. Regularly audit user privileges to ensure minimal necessary access, reducing the impact of compromised accounts. 8. Engage in vulnerability scanning and penetration testing focused on web application security to detect similar issues.
