When `commit` or `tag` objects contain ambiguous or malformed headers, `go-git`\u2019s decoded representation may expose values differently from how Git itself would interpret or reject the same object.\n\nAdditionally, `go-git`\u2019s commit signing and verification logic operates over commit data reconstructed from `go-git`\u2019s 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.\n\nThis 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.\n\n### Patches\nUsers 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.\n\n### Credit\n\nThanks to @bugbunny-research (https://bugbunny.ai/) for reporting this to `sigstore/gitsign`, and to @wlynch, @patzielinski and @adityasaky for coordinating the disclosure with the `go-git` project. :bow: :1st_place_medal: \n\nThanks to @wayphinder for reporting this to the `go-git` project. :bow:",

  "details": "### Impact\nA path validation issue in `go-git` could allow crafted repository data to affect files outside the intended checkout target, including the repository\u0027s `.git` directory.\n\nThese 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.\n\nUsing 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.\n\nHowever, 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.\n\nIt 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.\n\n### Patches\nUsers 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.\n\n### Credits\nThanks to @kodareef5, @AyushParkara and @N0zoM1z0 for reporting this to the go-git project in three separate reports. \ud83d\ude47",

  "details": "### Impact\n\n`go-git`\u0027s 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 `\u0027` becomes the `\u0027\\\u0027\u0027` close-escape-reopen sequence and the whole path round-trips as a single quoted argument.\n\nA 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\u0027s command-execution context. SSH servers that tokenize the exec command without shell evaluation, including the canonical `git-shell` setup, are not affected.\n\nThe 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\u0027s wire format and prevents `go-git` from being a vehicle for reaching shell-evaluating servers through attacker-influenced repository paths.\n\n### Patches\n\nUsers should upgrade to a patched version in order to mitigate this issue. The fix ports `sq_quote_buf` from canonical Git into `go-git`\u0027s SSH transport so that the wire output is byte-identical to what `git` itself would send for the same input.\n\nVersions prior to `v5` are likely to be affected, users are recommended to upgrade to a supported go-git version.\n\n### Credit\n\nThanks to @N0zoM1z0 for reporting this to the `go-git` project. :bow:",

  "details": "### Impact\nMultiple path traversal issues exist across different components of `go-billy`. Insufficient path sanitization and boundary enforcement may allow crafted paths (e.g., using `..`) to escape intended base directories.\n\nWhile go-billy was not originally designed to provide a strong security boundary, some of these issues were inconsistent across some of the built-in implementations. This results in scenarios where applications relying on `go-billy` for some level of isolation may inadvertently expose access to unintended filesystem locations.\n\nThe `osfs.ChrootOS` implementation is notably affected by this vulnerability and is now deprecated in `v5`, removed at `v6`. Users are recommended to move on to `osfs.BoundOS` instead: `osfs.New(path, WithBoundOS())`.\n\nUsers requiring stronger security boundary enforcement are recommended to upgrade to `v6`, where the `osfs` implementation are backed by the [traversal-resistant](https://go.dev/blog/osroot) primitive [os.Root](https://pkg.go.dev/os#Root).\n\n### Patches\nUsers 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-billy` version.\n\n### Credits\nThanks to @faran66 and @vnykmshr for finding and separately reporting this issue privately to the go-git project. \ud83d\ude47",

  "details": "### Impact\nSeveral denial-of-service issues were identified in `go-git` when parsing maliciously crafted Git repository data.\n\nAn 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.\n\nThis 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.\n\nExploitation requires the ability to alter read-only files such as `.pack` or `.idx` from the local repository\u0027s `.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.\n\n### Patches\nUsers should upgrade to a patched version in order to mitigate this vulnerability.
