Summary
Data races in parc
Details

In the affected versions of this crate, LockWeak unconditionally implemented Send with no trait bounds on T. LockWeak doesn't own T and only provides &T. This allows concurrent access to a non-Sync T, which can cause undefined behavior like data races.

Severity ?
