CVE-2025-58334 is a high-severity vulnerability identified in JetBrains IDE Services versions prior to 2025.5.0.1086 and 2025.4.2.2164. The vulnerability is classified under CWE-862, which pertains to improper authorization. Specifically, this flaw allows users who do not have the appropriate permissions to escalate their privileges by assigning themselves high-privileged roles within the JetBrains IDE Services environment. The vulnerability has a CVSS v3.1 base score of 8.1, indicating a high impact with network attack vector, low attack complexity, requiring low privileges but no user interaction, and affecting confidentiality and integrity with no impact on availability. The flaw arises from insufficient authorization checks in role assignment functionality, enabling privilege escalation without proper validation. Although no known exploits are currently reported in the wild, the potential for misuse is significant given the nature of the affected product and the ease of exploitation. JetBrains IDE Services is widely used by software development teams for integrated development environments and related services, making this vulnerability particularly critical in environments where role-based access control is essential for maintaining security boundaries.

For European organizations, the impact of this vulnerability can be substantial. JetBrains IDE Services are commonly used across various industries including finance, technology, manufacturing, and government sectors in Europe. Unauthorized privilege escalation could lead to attackers gaining administrative control over development environments, potentially allowing them to alter source code, inject malicious code, access sensitive intellectual property, or disrupt development workflows. This could result in data breaches, intellectual property theft, and compromise of software supply chains. Given the critical role of software development in digital transformation initiatives across Europe, exploitation of this vulnerability could undermine trust in software integrity and lead to regulatory compliance issues under frameworks such as GDPR, especially if personal data or sensitive information is exposed or manipulated.

To mitigate this vulnerability, European organizations should promptly upgrade JetBrains IDE Services to version 2025.5.0.1086 or later, or 2025.4.2.2164 or later, where the issue has been addressed. Until patches are applied, organizations should enforce strict network segmentation and access controls to limit who can access the IDE Services. Implement multi-factor authentication (MFA) for all users with elevated privileges to reduce the risk of unauthorized access. Conduct thorough audits of role assignments and permissions within the IDE Services environment to detect any unauthorized privilege escalations. Additionally, monitoring and alerting should be enhanced around role changes and administrative actions within the service. Organizations should also review and tighten their internal policies regarding role management and ensure that least privilege principles are strictly enforced. Finally, consider isolating critical development environments from general user networks to reduce exposure.
