SKILL.md, lines 13–19
Vulnerability Type: Unpinned dependencies installed from external package registries
Risk Level: MediumVulnerable Code
bash # JavaScript/TypeScript npm install glin-profanity # Python pip install glin-profanityTechnical Analysis
The installation instructions retrieve
glin-profanityfrom npm or PyPI without specifying an exact version, integrity hash, lockfile, or other verification mechanism. Consequently, the code installed by users may differ from the version that was originally reviewed.Package installation and subsequent imports can execute package-controlled code with the privileges of the invoking user. In the npm ecosystem, lifecycle scripts may execute during installation. Python packages may also execute package code during build or installation, depending on the package format and installer behavior.
The audited project contains only
SKILL.md; it does not include the dependency's source code or controls that establish the integrity of the downloaded artifacts. This finding therefore represents an insecure dependency acquisition path, not evidence that the named package is currently malicious.Attack Path
- An attacker compromises the package publisher account, registry artifact, release workflow, or a transitive dependency.
- The attacker publishes a malicious release under the expected package name.
- A user follows the documented unpinned
npm installorpip installcommand. - The package manager resolves the compromised release because no exact reviewed version or integrity constraint is specified.
- Malicious code executes through an installation lifecycle hook, package build process, or later application import.
- The payload operates with the permissions of the user or service performing the installation or running the application.

Remediation Suggestions
-
Pin each dependency to a reviewed, immutable version rather than relying on the latest registry resolution:
bash npm install glin-profanity@<reviewed-version> --save-exact pip install glin-profanity==<reviewed-version> -
Commit and enforce ecosystem lockfiles, such as
package-lock.jsonfor npm and a hash-locked requirements file for Python. -
Require integrity verification:
- Use npm lockfile integrity metadata and reproducible clean installation with
npm ci. - Generate Python requirements with hashes and install using
pip install --require-hashes. - Verify package publisher identity, release provenance, and signatures where available.
- Use npm lockfile integrity metadata and reproducible clean installation with
-
Audit the pinned package and its transitive dependencies before recommending it, including npm lifecycle scripts and Python build configuration.
-
Use automated dependency monitoring to identify compromised, deprecated, or vulnerable releases while ensuring that updates undergo review before deployment.
-
Perform package installation and runtime execution in a least-privileged, isolated environment without unnecessary credentials or access to sensitive host resources.
