CVE-2025-31130: gitoxide does not detect SHA-1 collision attacks

• Severity: medium (CVSS 6.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-04-04 · updated 2026-06-17
• Weakness: CWE-328

Description

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
