CVE-2025-31130: Gitoxidelabs Gitoxide

Medium severity, CVSS 6.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Gitoxidelabs Gitoxide: before 0.42.0 (fixed in 0.42.0)
