SecureJoin: on windows, paths outside of the rootfs could be inadvertently produced

GHSA-6xv5-86q9-7xr8 / GO-2023-2048

More information

Details

Impact

For Windows users of github.com/cyphar/filepath-securejoin, until v0.2.4 it was possible for certain rootfs and path combinations (in particular, where a malicious Unix-style /-separated unsafe path was used with a Windows-style rootfs path) to result in generated paths that were outside of the provided rootfs.

It is unclear to what extent this has a practical impact on real users, but given the possible severity of the issue we have released an emergency patch release that resolves this issue.

Thanks to @​pjbgf for discovering, debugging, and fixing this issue (as well as writing some tests for it).

Patches

c121231e1276e11049547bee5ce68d5a2cfe2d9b is the patch fixing this issue. v0.2.4 contains the fix.

Workarounds

Users could use filepath.FromSlash() on all unsafe paths before passing them to filepath-securejoin.

v0.2.4

Compare Source

This release fixes a potential security issue in filepath-securejoin
when used on Windows (GHSA-6xv5-86q9-7xr8, which could be used to
generate paths outside of the provided rootfs in certain cases), as well
as improving the overall behaviour of filepath-securejoin when dealing
with Windows paths that contain volume names. Thanks to Paulo Gomes for
discovering and fixing these issues.

In addition, we've switched (at long last) to GitHub Actions and have
continuous integration testing on Linux, MacOS, and Windows.
