Executable is not position-independent (no PIE/ASLR)

The Mach-O is not built with PIE, weakening ASLR and making memory-corruption exploitation easier.

How it's exploited

Without PIE, the binary loads at a fixed address, so ASLR cannot randomize it. Memory-corruption exploits get a stable layout to build ROP chains against.

Why it matters

One of the platform's core exploit mitigations is switched off for your code.

How to fix it

  1. Build with -fPIC / PIE enabled (default in modern toolchains; find the flag or ancient toolchain that disabled it).
  2. Rebuild any bundled native libraries that were compiled without PIE.
