It's essentially this issue https://github.com/rust-lang/rust/issues/25860

The code used to exploit the bug in this library is here: https://github.com/Speykious/cve-rs/blob/main/src/lifetime_expansion.rs

As far as I understand, the bug basically makes it so you can trick Rust into thinking any lifetime is actually 'static. From that, you can do all kinds of bad stuff.
