Title
Heap Out-of-Bounds Read in Go Driver GSSAPI C Wrappers enables application crash or information leak
Summary
The mongo-go-driver repository contains CGo bindings for GSSAPI (Kerberos) authentication on Linux and macOS. The C wrapper implementation contains a heap out-of-bounds read vulnerability due to incorrect assumptions about string termination in the GSSAPI standard. Since GSSAPI buffers are not guaranteed to be null-terminated or have extra padding, this results in reading one byte past the allocated heap buffer.

Title
go-git: Improper parsing of specially crafted objects may lead to inconsistent interpretation compared to upstream Git
Summary
go-git is an extensible git implementation library written in pure Go. Prior to 5.19.0 and 6.0.0-alpha.3, go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object. Additionally, go-git’s commit signing and verification logic operates over commit data reconstructed from go-git’s parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository. This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed. This vulnerability is fixed in 5.19.0 and 6.0.0-alpha.3.

Title
go-git: Improper single-quote escaping in go-git SSH transport
Summary
go-git is an extensible git implementation library written in pure Go. Prior to 5.19.1 and 6.0.0-alpha.4, go-git's SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. This vulnerability is fixed in 5.19.1 and 6.0.0-alpha.4.

Title
go-git: Crafted repositories may modify main and submodule .git directories
Summary
go-git is an extensible git implementation library written in pure Go. Prior to 5.19.1 and 6.0.0-alpha.4, a path validation issue in go-git could allow crafted repository data to affect files outside the intended checkout target, including the repository's .git directory. These validations were introduced in upstream Git years ago, so the vulnerability arose from go-git drifting from those checks. This vulnerability is fixed in 5.19.1 and 6.0.0-alpha.4.

Vulnerability from github – Published: 2026-05-11 14:48 – Updated: 2026-06-08 23:42
VLAI
Summary
go-git's improper parsing of specially crafted objects may lead to inconsistent interpretation compared to upstream Git
Details
Impact
go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object.
Additionally, go-git’s commit signing and verification logic operates over commit data reconstructed from go-git’s parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository.
This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed.
Patches
Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.

Summary
mongo-go-driver has Heap Out-of-Bounds Read in GSSAPI Error Handling
Details
The mongo-go-driver repository contains CGo bindings for GSSAPI (Kerberos) authentication on Linux and macOS. The C wrapper implementation contains a heap out-of-bounds read vulnerability due to incorrect assumptions about string termination in the GSSAPI standard. Since GSSAPI buffers are not guaranteed to be null-terminated or have extra padding, this results in reading one byte past the allocated heap buffer.

Summary
go-git: Crafted repositories may modify main and submodule .git directories
Details
Impact
A path validation issue in go-git could allow crafted repository data to affect files outside the intended checkout target, including the repository's .git directory.
These validations were introduced in upstream Git years ago, so the vulnerability arose from go-git drifting from those checks. Some attack vectors were platform-specific: certain payloads affected only Windows users, others affected only macOS users, and some applied across all supported platforms.
Using non-descendant go-billy filesystem instances, or different filesystem types, for the Storer and Worktree may provide some isolation against .git directory manipulation. For example, users that store the .git directory through memfs while using osfs for the worktree are not affected by this vulnerability in the main repository, because repository metadata is not materialized inside the worktree filesystem.
However, this isolation does not necessarily apply when the repository contains submodules, since submodule dotgit directories may still be represented or materialized within the worktree context.
It is important to note that exploitation requires a maliciously crafted repository payload. Users should always exercise caution when interacting with repositories or Git servers they do not trust.
Patches
Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.

Summary
go-git: Improper single-quote escaping in go-git SSH transport
Details
Impact
go-git's SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. This diverges from canonical Git, which shell-quotes the path through sq_quote_buf so that an embedded ' becomes the '\'' close-escape-reopen sequence and the whole path round-trips as a single quoted argument.
A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. On SSH servers that evaluate the exec command through a shell (for example a user account whose login shell is /bin/sh or /bin/bash, or a ForceCommand wrapper that re-evaluates $SSH_ORIGINAL_COMMAND), those additional tokens execute in that account's command-execution context. SSH servers that tokenize the exec command without shell evaluation, including the canonical git-shell setup, are not affected.
The vulnerable behaviour is on the SSH server side, not in go-git: the same bytes can be produced by any SSH client. The change in go-git is defense-in-depth that restores parity with canonical Git's wire format and prevents go-git from being a vehicle for reaching shell-evaluating servers through attacker-influenced repository paths.
Patches
Users should upgrade to a patched version in order to mitigate this issue. The fix ports sq_quote_buf from canonical Git into go-git's SSH transport so that the wire output is byte-identical to what git itself would send for the same input.
Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.

Summary
go-git: Malformed Git object data may cause panics or resource exhaustion
Details
Impact
Several denial-of-service issues were identified in go-git when parsing maliciously crafted Git repository data.
An attacker may craft a malicious .pack, .idx or loose objects that causes an application using an affected version of go-git to panic or consume excessive resources.
This can lead to denial of service in applications that use go-git to clone, fetch, open, or otherwise process untrusted repositories or Git object data.
Exploitation requires the ability to alter read-only files such as .pack or .idx from the local repository's .git/objects/pack/ directory. Alternatively, the user would need to be interacting with a malicious remote server, which is not recommended and exposes users to a broader class of security risks beyond this issue.
Patches
Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.
