- Unpinned Global Installation of a Third-Party CLI Package## Vulnerability Details **File Location**: `SKILL.md:4` and `SKILL.md:40` **Vulnerability Type**: Unpinned third-party dependency installed globally **Risk Level**: Medium ### Vulnerable Code ```yaml compatibility: requires xmindmark CLI (install via pnpm install -g xmindmark) ``` ```markdown Use npm or pnpm to install the XMindMark CLI: `npm install -g xmindmark` ``` ### Technical Analysis The skill instructs users to install the `xmindmark` package globally without specifying a reviewed version, integrity hash, lockfile, or verified package source. Package resolution therefore depends on whichever release and transitive dependencies the configured npm registry serves at installation time. npm-compatible package installation can execute package lifecycle scripts with the privileges of the installing user. If the package, one of its dependencies, its publisher account, or the configured registry is compromised, following this instruction could execute attacker-controlled code. A global installation also gives the resulting executable system-wide visibility within the user's npm prefix, increasing the exposure compared with a project-local, version-locked dependency. This finding identifies supply-chain risk in the installation guidance. The audit found no evidence that the currently published `xmindmark` package is malicious. ### Attack Path 1. An attacker compromises the package publisher, a transitive dependency, or the registry used by the victim. 2. The attacker publishes or serves a malicious package release or dependency version containing a lifecycle script or altered CLI payload. 3. A user follows the skill's unpinned instruction: ```bash npm install -g xmindmark ``` 4. The package manager resolves the attacker-controlled version because no trusted version or integrity value is specified. 5. Malicious lifecycle code may execute during installation with the installing user's privileges. 6. The globally installed command may also execut ...[truncated 757 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `xmindmark` to a specifically reviewed version rather than resolving the latest release: ```bash npm install --save-exact xmindmark@<reviewed-version> ``` 2. Prefer a project-local dependency and invoke it through a package script or a version-locked local binary instead of installing it globally. 3. Commit and enforce a lockfile with integrity metadata for the package and all transitive dependencies. 4. Document the expected package registry and verified package identity to reduce dependency-confusion and registry-substitution risks. 5. Verify package provenance, signatures, checksums, and publisher ownership where supported. 6. Disable lifecycle scripts during installation when the reviewed package is compatible: ```bash npm install --ignore-scripts ``` 7. Run conversion in a restricted environment with minimal filesystem access, no unnecessary credentials, and limited network access. 8. Establish a dependency-update process in which new versions are reviewed and tested before changing the pinned version.
