### go-git missing validation decoding Index v4 files leads to panic
[CVE-2026-33762](https://nvd.nist.gov/vuln/detail/CVE-2026-33762) / [GHSA-gm2x-2g9h-ccm8](https://github.com/advisories/GHSA-gm2x-2g9h-ccm8)

<details>
<summary>More information</summary>

#### Details
##### Impact

`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.

An attacker able to supply a crafted `.git/index` file can cause applications using go-git to panic while reading the index. If the application does not recover from panics, this results in process termination, leading to a denial-of-service (DoS) condition.

Exploitation requires the ability to modify or inject a Git index file within the local repository in disk. This typically implies write access to the `.git` directory.

##### Patches

Users should upgrade to `v5.17.1`, or the latest `v6` [pseudo-version](https://go.dev/ref/mod#pseudo-versions), in order to mitigate this vulnerability.

##### Credit

go-git maintainers thank @&#8203;kq5y for finding and reporting this issue privately to the `go-git` project.

<details>
<summary>More information</summary>

#### Details
##### Impact

A vulnerability has been identified in which a maliciously crafted `.idx` file can cause asymmetric memory consumption, potentially exhausting available memory and resulting in a Denial of Service (DoS) condition.

Exploitation requires write access to the local repository's `.git` directory, it order to create or alter existing `.idx` files.

##### Patches

Users should upgrade to `v5.17.1`, or the latest `v6` [pseudo-version](https://go.dev/ref/mod#pseudo-versions), in order to mitigate this vulnerability.

##### Credit
