- Unpinned Third-Party Package Execution During Auth0 Setup## Vulnerability Details **File Location**: `SKILL.md`, line 69 **Vulnerability Type**: Supply-chain risk from unpinned package execution **Risk Level**: Medium **Vulnerable Code**: ```bash npx configure-auth0-token-vault ``` ### Technical Analysis The manual setup procedure instructs the user to execute `configure-auth0-token-vault` through `npx` without specifying a version or verifying package integrity. Consequently, the code resolved from the package registry at execution time may differ from the version reviewed when this Skill was published. The project contains no lockfile, checksum, vendored source, or other mechanism that constrains or verifies the package executed by this command. Because the setup process handles Auth0 configuration and authentication, a compromised registry account, malicious package release, or compromised transitive dependency could execute arbitrary code in a credential-sensitive context. This finding concerns the unpinned manual setup command, not the documented Auth0 network functionality itself. Authenticated requests and remote connection-status retrieval are consistent with the Skill's declared purpose. No evidence of deliberate token exfiltration was identified in the reviewed files. ### Attack Path 1. An attacker compromises the package, its publisher account, the package registry delivery path, or a transitive dependency. 2. The attacker publishes a malicious version under the expected package name. 3. A user follows the manual setup instructions and runs `npx configure-auth0-token-vault`. 4. `npx` resolves and downloads the mutable package version from the registry. 5. The malicious package executes with the invoking user's local privileges during Auth0 setup. 6. It may read accessible local files, environment variables, Auth0 setup material, or credentials exposed during the configuration flow and transmit them externally. ### Impact Assessment Successful exploitation co ...[truncated 529 chars]
- Remediation
- ## Remediation Suggestions 1. Pin the package to a specifically reviewed version, for example: ```bash npx --yes configure-auth0-token-vault@<reviewed-version> ``` 2. Verify the package publisher, provenance, signature, and registry integrity metadata before recommending execution. 3. Use a lockfile and integrity hashes where the installation workflow permits them. 4. Prefer setup functionality included in an already pinned and audited `auth0-tv` release rather than retrieving a separate executable package at runtime. 5. Publish the package source and reviewed commit or release identifier so users can correlate the executed artifact with audited code. 6. Run setup with minimum user privileges and avoid exposing unrelated secrets through environment variables. 7. Warn users not to record, share, or persist terminal output containing the client secret produced by the separate `auth0 apps show <APP_ID> --reveal-secrets` step.
