CVE-2026-57924: 
YouTrack vulnerability analysis and mitigation

CVE-2026-57924 is an information disclosure vulnerability in JetBrains YouTrack caused by incorrect default role configuration that exposes excessive user profile details to authenticated users. It affects all versions of JetBrains YouTrack before 2026.2.16593. The vulnerability was published on June 26, 2026, and a patch was made available in version 2026.2.16593. It carries a CVSS v3.1 base score of 5.3 (Medium) (JetBrains Advisory, Feedly).

The root cause is classified as CWE-276 (Incorrect Default Permissions), where the default role configuration in YouTrack grants authenticated users access to user profile details that should be restricted. The attack vector is network-based, requiring no privileges or user interaction, though exploitation is not fully automatable per NVD SSVC assessment. An authenticated attacker can query or browse user profile information that exceeds what their role should permit, resulting in unintended data exposure (Feedly).

Successful exploitation allows any authenticated network user to view sensitive user profile details that should be restricted under the default role configuration, constituting a confidentiality breach. There is no impact on integrity or availability. The exposure is limited to user profile data within the YouTrack instance, but could facilitate reconnaissance or social engineering against other users or administrators (Feedly).

JetBrains has released a patch in YouTrack version 2026.2.16593, which corrects the default role configuration to restrict access to user profile details appropriately. Organizations should upgrade to version 2026.2.16593 or later as the primary remediation. As an interim measure, administrators should review and audit default role configurations within their YouTrack instance, applying the principle of least privilege to limit information exposure until the upgrade can be performed (JetBrains Advisory).

Coverage of this vulnerability has been limited to automated vulnerability tracking feeds and aggregators.
