error: 1 vulnerability found!

This dependency has been bumped upstream (rust-lang/cargo#12731), but that fix has not yet made it into a version of the cargo crate on crates.io. When it does, we should bump the version of the cargo crate used in this project.

Note that the cargo-helpers crate is not exposed to users of this project, and is also not affected by this vulnerability. Regardless, we should bump its cargo crate dependency version as soon as a newer one is available.
