CVE-2025-64682 identifies a race condition vulnerability (CWE-362) in JetBrains Hub, a collaborative platform used for managing users and agents in development environments. The vulnerability exists in versions prior to 2025.3.104432 and allows an attacker with high privileges to bypass the Agent-user limit, which is a control mechanism designed to restrict the number of agents associated with a user. This race condition arises due to improper synchronization in the code, enabling concurrent operations to interfere with each other and bypass intended limits. The vulnerability does not impact confidentiality or availability but compromises integrity by allowing unauthorized agent-user associations. Exploitation requires network access and high privileges, but no user interaction is necessary. The CVSS v3.1 score is 2.7 (low), reflecting the limited impact and exploitation complexity. No known exploits have been reported in the wild, and no official patches have been linked at the time of publication. The flaw could be leveraged to circumvent licensing or operational constraints within JetBrains Hub, potentially leading to unauthorized resource usage or policy violations.

For European organizations, the primary impact of this vulnerability lies in the integrity of user-agent management within JetBrains Hub. Organizations that rely on strict agent-user limits for licensing compliance, resource allocation, or operational security could see these controls bypassed, leading to unauthorized agent deployments or usage. This could result in increased operational costs, licensing violations, or potential misuse of development infrastructure. While confidentiality and availability are not directly affected, the integrity compromise could undermine trust in system controls and complicate audit and compliance efforts. Given JetBrains Hub's popularity in software development environments, particularly in countries with strong IT sectors, the vulnerability could affect a broad range of enterprises, from small development teams to large corporations. The lack of known exploits reduces immediate risk, but the potential for future exploitation exists if patches are not applied promptly.

Organizations should monitor JetBrains' official channels for the release of patches addressing CVE-2025-64682 and apply them promptly once available. Until patched, restrict access to JetBrains Hub to only trusted, high-privilege users and enforce strict network segmentation to limit exposure. Implement monitoring and alerting for unusual agent-user associations or sudden changes in agent counts that could indicate exploitation attempts. Review and audit user and agent configurations regularly to detect anomalies. Consider implementing additional application-layer controls or custom scripts to enforce agent-user limits as a temporary safeguard. Educate administrators about the vulnerability and the importance of maintaining strict privilege separation. Finally, maintain an incident response plan tailored to JetBrains Hub environments to quickly address any exploitation attempts.
