CVE-2025-64482 is a Cross-Site Request Forgery (CSRF) vulnerability identified in Enalean's Tuleap software, an open-source suite designed to facilitate software development management and collaboration. The vulnerability specifically affects the file release system component of Tuleap Community Edition versions prior to 16.13.99.1762267347 and Enterprise Editions prior to 17.0-1, 16.13-6, and 16.12-9. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request, which the server processes with the user's privileges. In this case, the attacker can manipulate commit rules or immutable tags within an SVN repository managed by Tuleap. Such unauthorized changes can undermine the integrity of the source code by altering repository policies or locking/unlocking tags that control code immutability. The vulnerability requires the victim to be authenticated and to interact with a crafted malicious request, as indicated by the CVSS vector (User Interaction: Required, Privileges: Low). The CVSS score of 4.6 reflects a medium severity, with network attack vector and low attack complexity. While confidentiality is not impacted, integrity and availability of the repository can be compromised. No known exploits have been reported in the wild, but the risk remains significant for organizations relying on affected Tuleap versions for source code management. The issue has been addressed in the specified patched versions, which implement proper CSRF protections in the file release system to prevent unauthorized state-changing requests.

For European organizations, this vulnerability poses a risk to the integrity and availability of software development repositories managed via Tuleap. Unauthorized changes to commit rules or immutable tags could allow attackers to bypass development controls, potentially introducing malicious code or disrupting development workflows. This can lead to compromised software quality, delayed releases, and increased risk of supply chain attacks. Organizations in sectors with stringent software integrity requirements, such as finance, healthcare, and critical infrastructure, may face regulatory and operational impacts if such vulnerabilities are exploited. The medium severity indicates moderate risk, but the potential for cascading effects on software supply chains and collaboration processes elevates the importance of timely remediation. Since Tuleap is used globally and has adoption in European countries with active open-source and enterprise development communities, the threat is relevant across multiple industries.

European organizations should immediately verify their Tuleap version and upgrade to the fixed releases: Community Edition 16.13.99.1762267347 or Enterprise Editions 17.0-1, 16.13-6, and 16.12-9. In addition to patching, organizations should implement the following specific measures: 1) Enforce strict session management and use anti-CSRF tokens in all state-changing requests within Tuleap, ensuring that any custom integrations or plugins also adhere to these protections. 2) Conduct user training to recognize phishing and social engineering attempts that could facilitate CSRF attacks. 3) Restrict access to Tuleap instances via network segmentation and VPNs to limit exposure to untrusted networks. 4) Monitor repository changes for unusual modifications to commit rules or tags, using automated alerts to detect potential exploitation. 5) Review and harden SVN repository permissions to minimize the impact of unauthorized changes. 6) Regularly audit and update all development tools and dependencies to maintain security hygiene beyond Tuleap itself.
