Summary
Inventory fails to prohibit standard library access prior to initialization of Rust standard library runtime
Details

Affected versions allow arbitrary caller-provided code to execute before the lifetime of main.

If the caller-provided code accesses particular pieces of the standard library that require an initialized Rust runtime, such as std::io or std::thread, these may not behave as documented. Panics are likely; UB is possible.

The flaw was corrected by enforcing that only code written within the inventory crate, which is guaranteed not to access runtime-dependent parts of the standard library, runs before main. Caller-provided code is restricted to running at compile time.
