CVE-2022-2054Public exploit

Compile-time code execution via evaluated environment variables

Published Jun 12, 2022 · Updated Aug 3, 2024

Code injection in Nuitka before 0.9 allows local users to execute arbitrary Python code during compilation through crafted environment variables. Nuitka's restart path passes NUITKA_PYTHONPATH, NUITKA_NAMESPACES, and NUITKA_PTH_IMPORTED through Python eval() rather than parsing them as literals. An attacker who controls the compiler process environment can run code with that process's privileges when Nuitka restarts itself.
