- Unpinned Third-Party CLI Introduces Supply-Chain Risk## Vulnerability Details **File Location**: `SKILL.md`, lines 8–11 **Vulnerability Type**: Unpinned third-party npm dependency **Risk Level**: Medium ```yaml install: method: npm package: "@_xtribe/cli" postInstall: "tribe login" ``` ### Technical Analysis The skill requires installation of the external npm package `@_xtribe/cli` without specifying an exact version, lockfile, or integrity hash. Consequently, installation can resolve to a package release that differs from the version originally reviewed. The installed CLI is subsequently trusted to authenticate the user and access sensitive development information, including coding sessions, project context, knowledge documents, and imported project data. The repository contains no source code for the dependency, so its implementation, lifecycle scripts, data handling, and network behavior could not be independently audited. This finding does not establish that the current package is malicious. The vulnerability is the mutable and unverified trust boundary created by installing an unpinned external package and then granting it access to sensitive development context. ### Attack Path 1. An attacker compromises the npm publisher account, package distribution process, or a future release of `@_xtribe/cli`. 2. A user installs the skill, and npm resolves the unpinned package reference to the compromised release. 3. Malicious package code executes during installation or when the `tribe` command is invoked. 4. The user runs `tribe login`, giving the compromised CLI access to authentication material or an authenticated session. 5. The CLI is used to search sessions, synchronize knowledge, import projects, or orchestrate agents. 6. The compromised dependency can access or transmit information available through those operations and may perform actions using the authenticated user's privileges. ### Impact Assessment Successful exploitation could expose authenticatio ...[truncated 564 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `@_xtribe/cli` to an exact, security-reviewed version rather than allowing mutable version resolution. 2. Supply a lockfile and verify the package with a trusted integrity hash or signed provenance before installation. 3. Review the package source, transitive dependencies, lifecycle scripts, network endpoints, and telemetry behavior for each upgrade. 4. Disable npm lifecycle scripts during installation where they are unnecessary, then invoke only explicitly reviewed setup operations. 5. Require explicit user approval before authentication, project import, knowledge synchronization, telemetry activation, or access to coding-session data. 6. Use a least-privilege account and narrowly scoped credentials for the CLI. 7. Document what data leaves the local environment, where it is transmitted, how it is retained, and how users can revoke credentials and delete synchronized data. 8. Execute the CLI in a restricted environment with limited filesystem and network access when feasible.
