CVE-2026-86501: In JetBrains IntelliJ IDEA before 2026.2.2 terminal command input could be written to idea.log

LowCVSS 2.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 11/100)

  • 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: 0.39% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: JetBrains IntelliJ IDEA 2026.2.2.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to JetBrains IntelliJ IDEA 2026.2.2 or later.
