Medium (6.5) in rust-lang cargo. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in cargo 0.97.0.
Cargo incorrectly handled symlinks inside of crate tarballs downloaded from third-party registries, allowing a malicious crate to override the source code of another crate from the same registry. The severity of the vulnerability is **medium** for users of third-party registries. Users of crates.io are **not affected**, as crates.io forbids uploading crates containing any symlink.
