CVE-2026-57925 Overview
CVE-2026-57925 affects JetBrains YouTrack versions before 2026.2.16593. The vulnerability stems from improper access control [CWE-862] that allows unauthorized reading of saved queries and tags. Attackers can access this information over the network without authentication or user interaction.
JetBrains addressed the flaw in YouTrack build 2026.2.16593. The issue is limited to information disclosure and does not impact integrity or availability of the affected system. Organizations running self-managed YouTrack instances should upgrade to the fixed release.
Critical Impact
Unauthenticated network-based attackers can enumerate saved queries and tags, potentially exposing sensitive project metadata, filter logic, and organizational taxonomy stored within YouTrack.
Affected Products
- JetBrains YouTrack versions prior to 2026.2.16593
- Self-managed YouTrack Server deployments
- YouTrack instances exposed to untrusted networks
Discovery Timeline
- 2026-06-26 - CVE-2026-57925 published to NVD

Technical Details for CVE-2026-57925
Vulnerability Analysis
The vulnerability is a missing authorization flaw [CWE-862] in JetBrains YouTrack. YouTrack failed to enforce access checks on endpoints that return saved queries and tags. As a result, network-reachable clients can request this data without appropriate permissions.
Saved queries and tags in YouTrack often encode business logic, project structure, workflow states, and filtering conditions used by teams. Exposure of these artifacts can leak internal project names, categorization schemes, and search patterns that reveal organizational priorities.
The attack requires no privileges and no user interaction. The scope is limited to confidentiality, with no impact on integrity or availability of YouTrack data.
Root Cause
The root cause is missing authorization enforcement on API paths that serve saved query and tag metadata. YouTrack did not verify that the requesting principal held the required permission to read these resources before returning them.
Attack Vector
An attacker sends crafted requests over the network to a vulnerable YouTrack instance. Because authorization checks are absent for the affected endpoints, the server returns saved queries and tags to the attacker. The vulnerability is exploitable remotely without credentials.
The vulnerability is described in prose only. No public proof-of-concept exploit code is available at this time. Refer to the JetBrains Security Issues Fixed advisory for vendor details.
Detection Methods for CVE-2026-57925
Indicators of Compromise
- Anomalous HTTP GET requests targeting YouTrack saved-query or tag API endpoints from unauthenticated sessions
- Bursts of enumeration-style requests originating from a single external IP against a YouTrack host
- Access log entries showing successful 200 OK responses to sensitive metadata endpoints without prior authentication events
Detection Strategies
- Review YouTrack access logs for requests to query and tag endpoints that lack corresponding authentication tokens or session cookies
- Correlate web application firewall (WAF) telemetry with YouTrack logs to identify scanning behavior against the affected build range
- Compare the reported YouTrack build number against 2026.2.16593 to identify vulnerable instances across the estate
Monitoring Recommendations
- Forward YouTrack application and reverse-proxy logs to a centralized SIEM for retention and analytics
- Alert on unauthenticated requests to /api/ paths that return non-empty JSON payloads
- Track outbound egress from YouTrack hosts to detect follow-on data exfiltration after enumeration
How to Mitigate CVE-2026-57925
Immediate Actions Required
- Upgrade JetBrains YouTrack to version 2026.2.16593 or later on all self-managed deployments
- Inventory internet-exposed YouTrack instances and restrict access to trusted networks pending patch deployment
- Rotate any API tokens or integration credentials if unauthorized access is suspected during review
Patch Information
JetBrains fixed the improper access control issue in YouTrack build 2026.2.16593. Administrators should consult the JetBrains Security Issues Fixed page for full remediation guidance and download the current release from the vendor's distribution channel.
Workarounds
- Place YouTrack behind a reverse proxy or VPN that enforces authentication before requests reach the application
- Restrict network access to YouTrack management endpoints using firewall rules or IP allow-lists
- Disable public access to YouTrack until the patched build is installed
# Example: restrict YouTrack access at the network layer with iptables
iptables -A INPUT -p tcp --dport 8080 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
