How to Fix GHSA-x5c7-x7m2-rhmf

To remediate this vulnerability, upgrade all affected Go.mozilla.org/sops/v3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

go.mozilla.org/sops/v3 fixed: 3.7.1 
Upgrade go.mozilla.org/sops/v3 to 3.7.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for go.mozilla.org/sops/v3

How to Check if You Are Affected

To determine whether your application is affected by GHSA-x5c7-x7m2-rhmf, inspect your project dependencies for Go.mozilla.org/sops/v3:

inspect dependencies for go.mozilla.org/sops/v3

Analyze the terminal output to locate any version of Go.mozilla.org/sops/v3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.7.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

This vulnerability is classified under General Security Weakness. In Go.mozilla.org/sops/v3, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Windows users using the sops direct editor option (`sops file.yaml`) can have a local executable named either `vi`, `vim`, or `nano` executed if running sops from `cmd.exe` This attack is only viable if an attacker is able to place a malicious binary within the directory you are running sops from. As well, this attack will only work when using `cmd.exe` or the Windows C library [SearchPath function](https://docs.microsoft.com/en-us/windows/win32/api/processenv/nf-processenv-searchpatha). This is a result of these Windows tools including `.` within their `PATH` by default. **If you are using sops within untrusted directories on Windows via `cmd.exe`, please upgrade immediately** **As well, if you have `.` within your default $PATH, please upgrade immediately.** More information can be found on the official Go blog: https://blog.golang.org/path-security ### Patches The problem has been resolved in v3.7.1 Now, if Windows users using cmd.exe run into this issue, a warning message will be printed: `vim resolves to executable in current directory (.\vim.exe)` ### References * https://blog.golang.org/path-security ### For more information If you have any questions or comments about this advisory: * Open a discussion in [sops](https://github.com/mozilla/sops/discussions)
