CVE-2025-50179 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 team collaboration. This vulnerability affects Tuleap Community Edition versions prior to 16.8.99.1749830289 and Tuleap Enterprise Edition versions prior to 16.9-1. The flaw allows an attacker to trick authenticated users into performing unintended actions, specifically altering the 'canned responses' feature within the application. Canned responses are predefined text snippets used to streamline communication or issue handling, and unauthorized modification could disrupt workflows or inject misleading information. The vulnerability requires the victim to be authenticated (privileged) and involves user interaction, as the victim must visit a maliciously crafted webpage or link. The CVSS v3.1 base score is 4.6, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L) shows that the attack is network exploitable with low attack complexity, requires privileges, and user interaction, and impacts integrity and availability but not confidentiality. No known exploits are currently reported in the wild. The issue has been addressed in Tuleap Community Edition 16.8.99.1749830289 and Enterprise Edition 16.9-1 through patches that mitigate the CSRF risk, likely by implementing anti-CSRF tokens or similar protections.

For European organizations using Tuleap, this vulnerability could lead to unauthorized modification of canned responses, potentially causing misinformation, workflow disruption, or social engineering opportunities within development and collaboration processes. While it does not directly compromise confidentiality, the integrity and availability of certain collaboration features are at risk. This could degrade operational efficiency, introduce errors in issue tracking or communication, and potentially facilitate further attacks if attackers manipulate responses to mislead users. Organizations relying heavily on Tuleap for project management or compliance tracking may face increased operational risk. Given the requirement for user interaction and privileges, the threat is more pronounced in environments where users have elevated permissions and may be targeted via phishing or malicious links. The absence of known exploits reduces immediate risk but does not eliminate the potential for future exploitation, especially as the vulnerability is publicly disclosed.

1. Immediate upgrade to Tuleap Community Edition 16.8.99.1749830289 or Enterprise Edition 16.9-1 to apply the official patch addressing the CSRF vulnerability. 2. Implement strict Content Security Policy (CSP) headers to reduce the risk of malicious cross-site requests. 3. Educate users, especially those with privileged access, about the risks of clicking on untrusted links or visiting suspicious websites while authenticated to Tuleap. 4. Review and restrict user privileges to the minimum necessary to reduce the impact of potential CSRF attacks. 5. Monitor application logs for unusual changes to canned responses or other configuration settings that could indicate exploitation attempts. 6. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block suspicious CSRF attack patterns targeting Tuleap endpoints. 7. Regularly audit and test the application environment for CSRF and other web vulnerabilities to ensure ongoing protection.
