CVE-2025-61982

Code execution via auto-compiled codeStream directives

Published Feb 18, 2026 · Updated Feb 18, 2026

Code injection in OpenCFD Ltd OpenFOAM 2506 allows attackers to execute arbitrary code by supplying a crafted simulation file. The #codeStream directive automatically compiles and executes embedded C++ from user-supplied dictionary files, including system() calls. Processing an untrusted simulation while allowSystemOperations retains its default true value is sufficient; resulting code runs with the local user's privileges.
