Hi,

The following vulnerability was published for rust-gix-features.

CVE-2025-31130[0]:
| gitoxide is an implementation of git written in Rust. Before 0.42.0,
| gitoxide uses SHA-1 hash implementations without any collision
| detection, leaving it vulnerable to hash collision attacks. gitoxide
| uses the sha1_smol or sha1 crate, both of which implement standard
| SHA-1 without any mitigations for collision attacks. This means that
| two distinct Git objects with colliding SHA-1 hashes would break the
| Git object model and integrity checks when used with gitoxide. This
| vulnerability is fixed in 0.42.0.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
