CVE-2025-58334: JetBrains IDE Services Privilege Escalation

CVE-2025-58334 Overview

CVE-2025-58334 is a missing authorization vulnerability [CWE-862] affecting JetBrains IDE Services. Authenticated users without appropriate permissions can assign high-privileged roles to themselves. The flaw enables vertical privilege escalation within the IDE Services management plane, undermining the platform's role-based access control model.

The issue affects JetBrains IDE Services builds before 2025.5.0.1086 and 2025.4.2.2164. JetBrains has released fixed builds addressing the authorization gap. Organizations using IDE Services to manage developer tooling, licenses, and plugin distribution should upgrade promptly.

Critical Impact
A low-privileged authenticated user can self-assign administrative roles, gaining full control over IDE Services configuration, license distribution, and plugin policy management.

Affected Products

JetBrains IDE Services versions before 2025.5.0.1086
JetBrains IDE Services versions before 2025.4.2.2164
Deployments exposing IDE Services role management endpoints to authenticated users

Technical Details for CVE-2025-58334

Vulnerability Analysis

The vulnerability stems from missing authorization checks on role assignment operations within JetBrains IDE Services. The application authenticates the requesting user but fails to verify whether that user holds the permissions required to modify role assignments. An attacker with a valid low-privileged account can invoke the role assignment functionality and grant themselves administrative privileges.

IDE Services centralizes management of JetBrains IDEs across enterprise developer fleets. Administrative roles control license allocation, plugin policies, AI assistant configuration, and integration with version control and CI systems. Escalation to an administrative role grants control over these capabilities.

The impact extends beyond the IDE Services instance. An attacker with administrative privileges can distribute malicious plugins, alter update channels, or weaken plugin signature policies, creating a foothold for supply chain attacks against developer workstations.

Root Cause

The root cause is an authorization check omitted from the role assignment workflow [CWE-862]. The server-side handler trusts client-supplied role assignment requests without validating that the calling principal possesses the role:assign or equivalent administrative permission.

Attack Vector

Exploitation requires network access to the IDE Services instance and valid low-privileged credentials. The attacker issues an authenticated request to the role management endpoint targeting their own user identity and a high-privileged role. The server processes the request without authorization validation and persists the role change. No user interaction is required, and exploit complexity is low.

No public proof-of-concept code is available for CVE-2025-58334. Refer to the JetBrains Security Issues Fixed advisory for vendor technical details.

Detection Methods for CVE-2025-58334

Indicators of Compromise

Role assignment audit events where the actor and target user fields are identical
Role assignment events performed by accounts that previously held only end-user permissions
Unexpected changes to plugin repository configuration, license server settings, or AI assistant policies
New administrative sessions originating from IP addresses associated with non-administrative users

Detection Strategies

Review IDE Services audit logs for role escalation events and correlate them with the originating account's prior permission level
Alert on any self-targeted role assignment operation, which should never occur in normal administrative workflows
Baseline the set of accounts authorized to perform role assignment and flag deviations
Monitor API access to role management endpoints from accounts outside the administrative group

Monitoring Recommendations

Forward IDE Services audit and access logs to a centralized SIEM for retention and correlation
Track plugin repository changes, update channel modifications, and license server reconfiguration as high-value events
Correlate IDE Services privilege changes with downstream developer endpoint activity to detect supply chain abuse attempts

How to Mitigate CVE-2025-58334

Immediate Actions Required

Upgrade JetBrains IDE Services to version 2025.5.0.1086 or 2025.4.2.2164 or later
Audit existing role assignments and revoke any administrative roles granted to users who should not hold them
Rotate API tokens and service credentials issued by IDE Services after remediation
Restrict network access to the IDE Services management interface to trusted administrative networks

Patch Information

JetBrains has released fixed builds 2025.5.0.1086 and 2025.4.2.2164 addressing the missing authorization check. See the JetBrains Security Issues Fixed advisory for the official remediation guidance and download links.

Workarounds

Place IDE Services behind a reverse proxy that restricts access to the role management endpoints to administrator IP ranges until patching is complete
Reduce the number of authenticated user accounts on the IDE Services instance to the minimum required
Enable enhanced audit logging and review role assignment events daily during the remediation window

bash

# Verify IDE Services build after upgrade
curl -sS https://ide-services.example.com/api/version \
  -H "Authorization: Bearer $TOKEN" | jq '.build'

# Expected output (or later):
# "2025.5.0.1086"
