Pull request overview
Back-ports hardened HTTP redirect handling to align with git’s http.followRedirects = initial default behavior, reducing the risk of unsafe redirect following and credential leakage during discovery.
Changes:
- Introduces FollowRedirects policy (defaulting to "initial") and wraps http.Client.CheckRedirect to enforce it.
- Tags the /info/refs discovery request as “initial” and converts ModifyEndpointIfRedirect to return errors for unsafe/invalid redirects (scheme, tail mismatch, etc.).
- Updates and adds tests covering redirect policy behavior, endpoint modification errors, and credential clearing rules.

If 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. An attacker controlling or influencing the redirect target can capture these credentials and potentially reuse them to access the victim’s repositories or other resources, depending on the scope of the credential. **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. ##### Patches Users 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. The 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. ##### Credit Thanks to the 3 separate reports from @​celinke97, @​N0zoM1z0 and @​AyushParkara.

If 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. An attacker controlling or influencing the redirect target can capture these credentials and potentially reuse them to access the victim’s repositories or other resources, depending on the scope of the credential. **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. ##### Patches Users 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. The 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. ##### Credit Thanks to the 3 separate reports from @​celinke97, @​N0zoM1z0 and @​AyushParkara. Thanks for finding and reporting this issue privately to the `go-git` project. 🙇 #### Severity - CVSS Score: 4.7 / 10 (Medium) - Vector String: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N` #### References - [https://github.com/go-git/go-git/security/advisories/GHSA-3xc5-wrhm-f963](https://github.com/go-git/go-git/security/advisories/GHSA-3xc5-wrhm-f963) - [https://github.com/go-git/go-git](https://github.com/go-git/go-git) This data is provided by [OSV](https://osv.dev/vulnerability/GHSA-3xc5-wrhm-f963) and the [GitHub Advisory Database](https://github.com/github/advisory-database) ([CC-BY 4.0](https://github.com/github/advisory-database/blob/main/LICENSE.md)). </details> --- ### Release Notes <details> <summary>go-git/go-git (github.com/go-git/go-git/v5)</summary> ### [`v5.18.0`](https://github.com/go-git/go-git/releases/tag/v5.18.0) [Compare Source](go-git/go-git@v5.17.2...v5.18.0) #### What's Changed - plumbing: transport/http, Add support for followRedirects policy by [@​pjbgf](https://github.com/pjbgf) in [#​2004](go-git/go-git#2004) **Full Changelog**: <go-git/go-git@v5.17.2...v5.18.0> ### [`v5.17.2`](https://github.com/go-git/go-git/releases/tag/v5.17.2) [Compare Source](go-git/go-git@v5.17.1...v5.17.2) #### What's Changed - build: Update module github.com/go-git/go-git/v5 to v5.17.1 \[SECURITY] (releases/v5.x) by [@​go-git-renovate](https://github.com/go-git-renovate)\[bot] in [#​1941](go-git/go-git#1941) - dotgit: skip writing pack files that already exist on disk by [@​pjbgf](https://github.com/pjbgf) in [#​1944](go-git/go-git#1944) :warning: This release fixes a bug ([#​1942](go-git/go-git#1942)) that blocked some users from upgrading to `v5.17.1`.
