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. Additionally, 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. 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."

  "details": "### Impact \n\nA 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`.\n\nFor context, clients fetch [`packfiles`](https://git-scm.com/docs/pack-protocol#_packfile_data) 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](https://git-scm.com/docs/pack-format) 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.\n\nNote 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.\n\n### Patches\n\nUsers should upgrade to `v5.16.5`, or the latest `v6` [pseudo-version](https://go.dev/ref/mod#pseudo-versions), in order to mitigate this vulnerability.\n\n### Workarounds\n\nIn case updating to a fixed version of `go-git` is not possible, users can run [git fsck](https://git-scm.com/docs/git-fsck) from the `git` cli to check for data corruption on a given repository. \n\n### Credit\n\nThanks @N0zoM1z0 for finding and reporting this issue privately to the `go-git` project.",

  "details": "### Impact\n`go-git` may leak HTTP authentication credentials when following redirects during smart-HTTP clone and fetch operations.\n\nIf a remote repository responds to the initial `/info/refs` request with a redirect to a different host, go-git updates the session endpoint to the redirected location and reuses the original authentication for subsequent requests. This can result in the credentials (e.g. Authorization headers) being sent to an unintended host.\n\nAn attacker controlling or influencing the redirect target can capture these credentials and potentially reuse them to access the victim\u2019s repositories or other resources, depending on the scope of the credential.\n\n**Clients using `go-git` exclusively with trusted remotes (for example, GitHub or GitLab), and over a secure HTTPS connection, are not affected by this issue.** The risk arises when interacting with untrusted or misconfigured Git servers, or when using unsecured HTTP connections, which is not recommended. Such configurations also expose clients to a broader class of security risks beyond this issue, including credential interception and tampering of repository data.\n\n### Patches\nUsers should upgrade to `v5.18.0`, or `v6.0.0-alpha.2`, 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\nThe patched versions add support for configuring [followRedirects](https://git-scm.com/docs/git-config#Documentation/git-config.txt-httpfollowRedirects). In line with upstream behaviour, the default is now `initial`, while users can opt into `FollowRedirects` or `NoFollowRedirects` programmatically.\n\n### Credit\nThanks to the 3 separate reports from @celinke97, @N0zoM1z0 and @AyushParkara.

  "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. Versions prior to `v5` are likely to be affected, users are recommended to upgrade to a supported `go-git` version.\n\n### Credits\ngo-git thanks @kodareef5, @AyushParkara and @N0zoM1z0 for reporting this in four separate reports. \ud83d\ude47",

An actor can send a malformed EventStream response frame containing a crafted header value type byte outside the valid range, which can cause the host process to terminate.\n\nImpacted versions: \u003c [2026-03-23](https://github.com/aws/aws-sdk-go-v2/releases/tag/release-2026-03-23)\n\n## Patches\nThis issue has been addressed in versions [2026-03-23](https://github.com/aws/aws-sdk-go-v2/releases/tag/release-2026-03-23) and above. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes. \n\n## Workarounds\nNot Applicable\n\n## References\nIf you have any questions or comments about this advisory, we ask that you contact [AWS/Amazon] Security via our [vulnerability reporting page](https://aws.amazon.com/security/vulnerability-reporting) or directly via email to [aws-security@amazon.com](mailto:aws-security@amazon.com).
