Unauthenticated remote code execution

Published Jul 22, 2026 · Updated Jul 22, 2026

Code injection in Fujitsu Software Linux openFT and Oracle Solaris openFT before 12.1D00 allows remote attackers to execute code. Fujitsu and the CNA have not published the affected component, input vector, or code-generation operation that permits execution. No authentication or user interaction is required; successful exploitation grants code execution on the Linux or Oracle Solaris host.
