Security readout for executives and security teams
Plain-English summary
This is a critical JetBrains YouTrack authentication bypass. In vulnerable versions, direct database access could lead to administrative YouTrack access, meaning an attacker could potentially take over issue tracking data and workflows. The bundle does not show active exploitation.
Executive priority
Treat this as urgent for any organization running YouTrack. The issue is critical because successful exploitation could give administrative control over issue tracking content, projects, users, and workflows.
Technical view
CVE-2026-62422 affects JetBrains YouTrack before fixed builds 2026.1.13757, 2025.3.148033, 2025.2.148048, 2025.1.148120, 2024.3.148430, and 2024.2.148429. It is CWE-306, missing authentication, with CVSS 3.1 score 10.0: network, low complexity, no privileges, no user interaction, scope changed.
Likely exposure
Any YouTrack instance below the listed fixed builds should be treated as exposed. The bundle does not clarify hosted versus self-managed exposure, database platforms, or exact environmental prerequisites beyond direct database access.
Exploitation context
No KEV listing is present, and the provided sources do not state active exploitation or public exploit availability. Risk remains severe because the described outcome is administrative access without authentication.
Researcher notes
The source data is sparse. It confirms affected version thresholds, CWE-306, CVSS 10.0, and the direct-database-access path to administrative access. It does not provide root cause detail, exploit indicators, patch diff context, or confirmed exploitation.
Mitigation direction
- Upgrade YouTrack to the applicable fixed build or later.
- Check JetBrains guidance for any temporary mitigations if immediate upgrade is not possible.
- Restrict and review direct database access paths to YouTrack data stores.
- Review administrative accounts and permissions for unexpected changes.
- Monitor YouTrack and database access logs for suspicious activity.
Validation and detection
- Identify all YouTrack instances and record exact build numbers.
- Compare each build against the fixed thresholds in the advisory.
- Confirm upgrades completed successfully and services restarted cleanly.
- Review admin users, groups, tokens, and permission changes.
- Check whether database access is limited to expected service identities.

Conservative CVE-to-ATT&CK context
These mappings and lookup hints may be relevant to the vulnerability behavior, CWE, affected product, or exposure path. Glexia-inferred context is not an official MITRE, ATT&CK, CWE, or CVE Program mapping.
ATT&CK lookup starting points
Use these exact CWE pages and searches to review the Glexia ATT&CK library from this CVE's weakness and description context.
CWE-306: Credential and account abuse lookup
Authentication and credential weaknesses can make valid-account abuse and credential telemetry useful review starting points. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCredential and access behavior lookup
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
Open ATT&CK lookupDatabase behavior lookup
The CVE wording references database injection or access, so collection and exfiltration review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Missing Authentication for Critical Function
Missing Authentication for Critical Function represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
