CVE-2026-57925: 
YouTrack vulnerability analysis and mitigation

CVE-2026-57925 is an improper access control vulnerability in JetBrains YouTrack that allows unauthorized reading of saved queries and tags. It affects all versions of YouTrack before 2026.2.16593 and was published on June 26, 2026. The vulnerability was assigned a CVSS v3.1 base score of 5.3 (Medium) by NVD, with an alternative score of 4.3 (Medium) noted by ENISA (JetBrains Advisory).

The root cause is classified as CWE-862 (Missing Authorization), meaning the application fails to perform proper authorization checks before granting access to saved queries and tags. An unauthenticated or low-privileged network attacker can exploit this flaw remotely with low attack complexity and no user interaction required, by sending crafted requests to YouTrack endpoints that expose restricted query and tag data. No technical write-ups or public proof-of-concept code have been identified at this time (JetBrains Advisory).

Successful exploitation allows any attacker to read saved queries and tags that should be access-controlled, potentially exposing sensitive search criteria, project organization details, and internal workflow configurations. The impact is limited to confidentiality — there is no integrity or availability impact — and the scope is confined to the YouTrack instance itself with no evidence of lateral movement potential (JetBrains Advisory).

JetBrains has released a patch in YouTrack version 2026.2.16593, which resolves the improper access control issue. Users should upgrade to version 2026.2.16593 or later as the primary remediation step. As a temporary workaround prior to patching, administrators should review and restrict YouTrack access to trusted and authenticated users only, limiting exposure of the affected functionality (JetBrains Advisory).

Coverage of this vulnerability has been limited to automated vulnerability tracking platforms and aggregators such as Vulners, Tenable, VulDB, and ENISA's EUVD. BeyondMachines noted it as part of a broader JetBrains patch release addressing multiple flaws across their application ecosystem (BeyondMachines). No notable researcher commentary or significant social media discussion has been observed.
