It has been classified as problematic. This vulnerability affects unknown code. The manipulation leads to array index. This vulnerability is documented as CVE-2026-33762. The attack needs to be performed locally. There is not any exploit available. Upgrading the affected component is recommended. Detailsinfo A vulnerability was found in go-git up to 5.17.0. It has been rated as problematic. This issue affects an unknown code block. The manipulation with an unknown input leads to a array index vulnerability. Using CWE to declare the problem leads to CWE-129. The product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. Impacted is availability. The summary by CVE is: 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. The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-33762 since 03/23/2026. The exploitation is known to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. Upgrading to version 5.17.1 eliminates this vulnerability.
