GitHub Vulnerability Alerts

CVE-2025-21613

Impact

An argument injection vulnerability was discovered in go-git versions prior to v5.13.

Successful exploitation of this vulnerability could allow an attacker to set arbitrary values to git-upload-pack flags. This only happens when the file transport protocol is being used, as that is the only protocol that shells out to git binaries.

Affected versions

Users running versions of go-git from v4 and above are recommended to upgrade to v5.13 in order to mitigate this vulnerability.

Workarounds

In cases where a bump to the latest version of go-git is not possible, we recommend users to enforce restrict validation rules for values passed in the URL field.

CVE-2025-21614

Impact

A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.13. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in go-git clients.

This is a go-git implementation issue and does not affect the upstream git cli.

Patches

Users running versions of go-git from v4 and above are recommended to upgrade to v5.13 in order to mitigate this vulnerability.

Workarounds

In cases where a bump to the latest version of go-git is not possible, we recommend limiting its use to only trust-worthy Git servers.

CVE-2026-25934

Impact

A vulnerability was discovered in go-git whereby data integrity values for .pack and .idx files were not properly verified. This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found.

For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly.

Note that the lack of verification of the packfile checksum has no impact on the trust relationship between the client and server, which is enforced based on the protocol being used (e.g. TLS in the case of https:// or known hosts for ssh://). In other words, the packfile checksum verification does not provide any security benefits when connecting to a malicious or compromised Git server.

Patches

Users should upgrade to v5.16.5, or the latest v6 pseudo-version, in order to mitigate this vulnerability.

Workarounds

In case updating to a fixed version of go-git is not possible, users can run git fsck from the git cli to check for data corruption on a given repository.

CVE-2026-33762

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, in order to mitigate this vulnerability.

Credit

go-git maintainers thank @​kq5y for finding and reporting this issue privately to the go-git project.

CVE-2026-34165

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, in order to mitigate this vulnerability.

Credit

The go-git maintainers thank @​kq5y for finding and reporting this issue privately to the go-git project.
