JetBrains Patches CVSS 10 Authentication Bypass Affecting 15 Million Developers

**JetBrains security advisory:** JetBrains fixed three vulnerabilities affecting Hub, YouTrack, and GoLand — the most severe is an authentication bypass (CVE-2026-50242, CVSS 10.0) that could allow administrative takeover; fixes are available for affected builds and no evidence of in-the-wild exploitation has been observed, so self-hosted instances should update immediately.
