Affected: Go standard library syscall, Go standard library os

os.OpenFile(path, os.O_CREATE|O_EXCL) behaved differently on Unix and Windows systems when the target path was a dangling symlink. On Unix systems, OpenFile with O_CREATE and O_EXCL flags never follows symlinks. On Windows, when the target path was a symlink to a nonexistent location, OpenFile would create a file in that location. OpenFile now always returns an error when the O_CREATE and O_EXCL flags are both set and the target path is a symlink.

 https://cve.radiocsirt.org/vuln/ghsa-37cx-329c-33x3 GHSA-37cx-329c-33x3 — go-git improperly verifies data integrity values for .idx and .pack files 2026-10-03T09:13:19.923039+00:00

Affected: Go: github.com/go-git/go-git/v5

### 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`](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.

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](https://go.dev/ref/mod#pseudo-versions), 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](https://git-scm.com/docs/git-fsck) from the `git` cli to check…
