CVE-2025-58334 is a high-severity vulnerability (CWE-862: Missing Authorization) affecting JetBrains IDE Services versions prior to 2025.5.0.1086 and 2025.4.2.2164. This vulnerability allows users who do not have the appropriate permissions to escalate their privileges by assigning themselves high-privileged roles within the IDE Services environment. The flaw arises due to insufficient authorization checks when role assignments are performed, enabling unauthorized privilege escalation. The CVSS v3.1 score of 8.1 reflects the vulnerability's network exploitability (AV:N), low attack complexity (AC:L), requirement for low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality and integrity (C:H/I:H), with no impact on availability (A:N). Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the potential for unauthorized users to gain elevated access rights, potentially compromising sensitive source code, project configurations, and developer credentials managed within JetBrains IDE Services. This vulnerability is particularly critical in environments where JetBrains IDE Services are used for collaborative development and continuous integration workflows, as it could lead to unauthorized code changes, data leakage, or sabotage of development pipelines.

For European organizations, the impact of CVE-2025-58334 could be substantial, especially for those relying on JetBrains IDE Services for software development and DevOps processes. Unauthorized privilege escalation could lead to exposure or manipulation of proprietary source code, intellectual property theft, and disruption of software development lifecycles. This could result in financial losses, reputational damage, and regulatory non-compliance, particularly under GDPR if personal data is indirectly exposed through compromised development environments. Additionally, organizations in sectors such as finance, healthcare, and critical infrastructure that depend on secure software development practices may face increased risks of targeted attacks exploiting this vulnerability to implant backdoors or malicious code. The lack of required user interaction and the ability to exploit remotely over the network further increase the threat level, making it easier for attackers to compromise systems without detection.

To mitigate CVE-2025-58334, European organizations should immediately upgrade JetBrains IDE Services to version 2025.5.0.1086 or later, where the vulnerability is patched. Until patching is possible, organizations should enforce strict access controls and monitor role assignment activities within the IDE Services environment. Implement multi-factor authentication (MFA) for all users with elevated privileges to reduce the risk of unauthorized access. Audit and restrict permissions to the minimum necessary roles, applying the principle of least privilege rigorously. Network segmentation should be employed to limit access to IDE Services to trusted internal networks and VPNs. Additionally, implement logging and real-time alerting for any anomalous privilege escalation attempts or role changes. Conduct regular security assessments and penetration testing focused on authorization controls within development tools. Finally, educate developers and administrators about the risks of privilege escalation and the importance of promptly applying security updates.
