├ ID: RUSTSEC-2024-0370
├ Advisory: https://rustsec.org/advisories/RUSTSEC-2024-0370
├ proc-macro-error's maintainer seems to be unreachable, with no commits for 2 years, no releases pushed for 4 years, and no activity on the GitLab repo or response to email.
proc-macro-error also depends on `syn 1.x`, which may be bringing duplicate dependencies into dependant build trees.
## Possible Alternative(s)
- [proc-macro-error2](https://crates.io/crates/proc-macro-error2)
├ Announcement: https://gitlab.com/CreepySkeleton/proc-macro-error/-/issues/20
├ Solution: No safe upgrade is available!
├ proc-macro-error v1.0.4
└── syn_derive v0.1.8

https://crates.io/crates/proc-macro-error2 is the only published replacement so far as I can see. There are a few other forks around tho.
