Aheui interpreter

1,684 downloads · published 2024-04-10 · source View on crates.io
Reviewed by Bitbison: secrets-exposureaheui's interpreter rpaheui requires rustpython ^0.3.1, whose VM copies every environment variable set at compile time into the library. Every aheui binary carries the full environment of the machine that compiled it, tokens and keys included, and no release can reach the fixed rustpython 0.6.

aheui 0.0.1 puts its compile environment inside the binary through rustpython-vm 0.3

secrets-exposureCovers 0.0.1Reviewed by BitbisonUpdated 2026-11-04

aheui's interpreter rpaheui requires rustpython ^0.3.1, whose VM copies every environment variable set at compile time into the library. Every aheui binary carries the full environment of the machine that compiled it, tokens and keys included, and no release can reach the fixed rustpython 0.6.

What the package does

aheui is a command-line interpreter for Aheui, an esoteric programming language written in Hangul. It is a thin wrapper over the rpaheui crate, which runs the reference interpreter on RustPython.

Compiling aheui compiles rustpython-vm 0.3.1, whose build script writes every environment variable of the compile into a source file that the library includes. The finished aheui executable therefore holds, as plain strings, every variable that was set when it was compiled: on a developer machine or a CI runner that means tokens such as GITHUB_TOKEN, cloud keys and registry tokens. Anyone with a copy of the binary can read them with strings, and Python code run by the embedded interpreter can read them through sysconfig.get_config_vars().

What the code does

  • aheui's Cargo.toml depends on rpaheui 0.0.1, and its Cargo.lock pins rustpython-vm 0.3.1.
  • rpaheui 0.0.1 (checksum 0991f824…b08d, as the crates.io index gives it) requires rustpython and rustpython-derive ^0.3.1. For a 0.x version that requirement stays within 0.3, so neither the locked nor a fresh resolution can reach rustpython 0.6.0, the first release without the dump.
  • rustpython-vm 0.3.x's build script writes $OUT_DIR/env_vars.rs from std::env::vars_os(), and src/stdlib/sysconfigdata.rs line 22 includes it in build_time_vars. The registry's review of rustpython-vm describes the mechanism; it is RUSTSEC-2026-0394.

aheui and rpaheui have one release each, both from April 10, 2024.

Conclusion

secrets-exposure: every aheui 0.0.1 binary contains the whole environment it was compiled in, through rustpython-vm 0.3.1, and no version requirement in the chain allows the fix.

Compile aheui only with a clean environment (env -i with just what cargo needs), never on a CI runner that holds secrets, and do not distribute a binary compiled elsewhere. If one has left the machine that compiled it, treat every secret in that environment as exposed and rotate it. A fix needs rpaheui to move to rustpython 0.6 or later.
