## Verdict summary
**Blocked & quarantined** — The redirect destination can receive the user's repository access token.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 1.0.16
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The bundle follows HTTP redirects for authenticated repository reads without removing or validating the authorization header. This can send a user's GitHub token to a redirect destination on another host, which is credential exfiltration.

## Latest scan

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Authenticated repository reads can leak GitHub credentials through an untrusted HTTP redirect.

- **Trigger:** A user runs a command that reads a private GitHub repository and the response redirects to a host controlled by an attacker.

- **Impact:** The redirect destination can receive the user's repository access token.

- **Evidence paths:** dist/sous.js

- **Review source:** ai\_review

- **Reviewed:** 2026-11-04T19:08:18.765Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The client follows the redirect while reusing the original authorization headers, with no destination-host validation.

- **Attack narrative:** When Sous reads a private GitHub repository, it can retrieve a token from the environment, Git credentials, or the GitHub CLI and attach it to an API request. If the response redirects to an attacker-controlled host, the client follows that location with the same headers. The redirected host can therefore receive the GitHub token.

- **Rationale:** The bundle follows HTTP redirects for authenticated repository reads without removing or validating the authorization header. This can send a user's GitHub token to a redirect destination on another host, which is credential exfiltration.

- **Network endpoints:** api.github.com, ${repository.host}/api/v3, redirect destination from the response Location header

### Review decision

- **Verdict:** Malicious

- **Confidence:** 94.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** GitHub repository reads can obtain tokens from environment variables, Git credentials, or the GitHub CLI and use them in an authenticated HTTP strategy., The authenticated request adds a bearer token to its headers., On a redirect, the code changes the request address and retries with the same headers, without checking that the new host is trusted., The initial GitHub API URL is api.github.com for github.com repositories; redirects can send its authorization header to another host.

- **Evidence against:** The package is a repository and AI configuration CLI, and its manifest has no install lifecycle hooks., Token lookup is scoped to the repository host, which is appropriate for the initial repository request., The redirect-following behavior is reached during repository reads, rather than by a package install hook.

## Affected versions and remediation

This report applies to @sous-io/sous@1.0.16.

- Avoid installing @sous-io/sous@1.0.16. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
