CVE-2025-62292 is a vulnerability classified under CWE-669 (Incorrect Resource Transfer Between Spheres) affecting SonarSource SonarQube, a widely used code quality and security analysis platform. In affected versions prior to 25.6, 2025.3 Commercial, and 2025.1.3 LTA, authenticated users with low privileges can query the /api/v2/users-management/users REST API endpoint. This endpoint improperly exposes user fields that should be restricted to administrators, notably including email addresses of other users. The flaw arises from insufficient access control checks on sensitive user data within the API, allowing unauthorized data disclosure. The vulnerability does not allow modification of data or disruption of service, but it leaks personally identifiable information (PII) that could be leveraged for social engineering or phishing attacks. Exploitation requires the attacker to have valid credentials but does not require further user interaction, making it relatively straightforward for insiders or compromised accounts to abuse. The CVSS v3.1 score is 4.3 (medium), reflecting network attack vector, low complexity, low privileges required, no user interaction, and limited confidentiality impact. No public exploits have been reported yet, but the exposure of email addresses in a developer-centric environment can facilitate targeted attacks. The issue highlights the importance of strict role-based access controls and API endpoint security in software development tools.

For European organizations, the primary impact is the unauthorized disclosure of user email addresses within SonarQube instances. This can lead to privacy violations under GDPR, as email addresses are personal data. Attackers could use this information to conduct spear-phishing campaigns targeting developers and administrators, potentially leading to credential theft or further compromise. While the vulnerability does not directly affect system integrity or availability, the indirect risks from social engineering and insider threats are significant. Organizations relying heavily on SonarQube for code quality and security analysis may face reputational damage if user data is leaked. Additionally, compliance risks arise due to inadequate protection of personal data. The vulnerability is particularly concerning in environments where low-privileged users are numerous or where credential compromise is more likely. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as the vulnerability is publicly disclosed.

To mitigate CVE-2025-62292, organizations should prioritize upgrading SonarQube to versions 25.6, 2025.3 Commercial, or 2025.1.3 LTA or later once patches are released. Until then, restrict access to the /api/v2/users-management/users endpoint by implementing strict role-based access controls and network segmentation to limit API access only to trusted administrators. Review and audit user privileges regularly to minimize the number of low-privileged users with access to the system. Employ multi-factor authentication (MFA) to reduce the risk of credential compromise. Monitor API usage logs for unusual access patterns that could indicate exploitation attempts. Additionally, educate users about phishing risks and implement email filtering solutions to detect and block targeted phishing campaigns. Consider deploying Web Application Firewalls (WAFs) with custom rules to block unauthorized API calls. Finally, maintain an incident response plan that includes procedures for handling data exposure incidents and GDPR notification requirements.
