Affected: CleanStart: external-secrets-fips

Package external-secrets-fips version 0.17.0-r2 fixes 75 vulnerabilities: CVE-2026-39820, CVE-2026-25679, CVE-2025-61726, CVE-2026-27143, CVE-2025-68121...

Billy is an interface filesystem abstraction for Go. Prior to 5.9.0, multiple path traversal issues exist across different components of go-billy. Insufficient path sanitization and boundary enforcement may allow crafted paths (e.g., using ..) to escape intended base directories. While go-billy was not originally designed to provide a strong security boundary, some of these issues were inconsistent across some of the built-in implementations. This results in scenarios where applications relying on go-billy for some level of isolation may inadvertently expose access to unintended filesystem locations. This vulnerability is fixed in 5.9.0.

Affected: Go: github.com/go-git/go-billy/v5, Go: github.com/go-git/go-billy/v6

### Impact Multiple path traversal issues exist across different components of `go-billy`. Insufficient path sanitization and boundary enforcement may allow crafted paths (e.g., using `..`) to escape intended base directories.

While go-billy was not originally designed to provide a strong security boundary, some of these issues were inconsistent across some of the built-in implementations. This results in scenarios where applications relying on `go-billy` for some level of isolation may inadvertently expose access to unintended filesystem locations.

The `osfs.ChrootOS` implementation is notably affected by this vulnerability and is now deprecated in `v5`, removed at `v6`. Users are recommended to move on to `osfs.BoundOS` instead: `osfs.New(path, WithBoundOS())`.

Users requiring stronger security boundary enforcement are recommended to upgrade to `v6`, where the `osfs` implementation are backed by the [traversal-resistant](https://go.dev/blog/osroot) primitive [os.Root](https://pkg.go.dev/os#Root).

### Patches Users 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-billy` version.

### Credits Thanks to @faran66 and @vnykmshr for finding and separately reporting this issue privately to the go-git project. 🙇
