Overview

CVE-2026-33762 is a low-severity vulnerability. It was published on March 31, 2026 and has a CVSS 3.1 base score of 2.8 (LOW).

This vulnerability has a CVSS 3.1 base score of 2.8, rated LOW. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

go-git is an extensible git implementation library written in pure Go. Prior to version 5.17.1, go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue. This issue has been patched in version 5.17.1.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
