CVE-2026-103492: In JetBrains YouTrack before 2026.2.19422 doS attack was possible via crafted PSD attachments

MediumCVSS 6.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.68% (FIRST EPSS); higher than 53% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: JetBrains YouTrack 2026.2.19422.

Low priority for now. Upgrade to JetBrains YouTrack 2026.2.19422 or later.
