CVE-2026-57924: 
YouTrack Analisi e mitigazione delle vulnerabilità

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 the same day (JetBrains). It carries a CVSS v3.1 base score of 5.3 (Medium) per NVD, and 4.3 (Medium) per JetBrains/ENISA, reflecting a low-severity confidentiality impact with no integrity or availability impact.

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 beyond what is appropriate. An attacker with a valid account can query the application over the network without elevated privileges to retrieve sensitive profile information that should be restricted by role-based access controls. No special conditions, user interaction, or complex attack chain is required beyond authentication (JetBrains). No public technical write-ups or proof-of-concept code have been identified at this time.

Successful exploitation results in unauthorized disclosure of user profile details within the YouTrack instance, representing a confidentiality impact. There is no impact to integrity or availability. The exposed information could include personal or organizational data about users (e.g., email addresses, names, or other profile fields), which could facilitate targeted phishing, social engineering, or account enumeration against the organization's development or project management team (JetBrains).

JetBrains has released a fix in YouTrack version 2026.2.16593. Organizations should upgrade to this version or later as the primary remediation step (JetBrains). As a supplementary measure, administrators should review and audit default role configurations within YouTrack to ensure user profile fields are restricted according to the principle of least privilege. Limiting network access to YouTrack instances to trusted users can also reduce exposure.

Coverage of this vulnerability has been limited to automated vulnerability tracking platforms and feeds, including Tenable, VulnDB, and ENISA's EUVD. No notable researcher commentary or significant community discussion has been identified beyond standard CVE publication and aggregation.
