yaml install: - id: npm kind: node package: axios bins: ["axios"]Technical Analysis
The skill requests installation of the
axiosnpm package without specifying an exact version or integrity constraint. Consequently, installation resolves mutable package-registry state rather than a release that was explicitly reviewed and approved.If the package, one of its transitive dependencies, or the associated registry account is compromised, a malicious future release could be selected during installation. npm lifecycle scripts may execute package-controlled code as part of installation unless explicitly disabled.
The declaration
bins: ["axios"]is also inconsistent with Axios's normal use as a JavaScript library. Expecting anaxiosexecutable may introduce installation or validation ambiguity and should be removed unless a reviewed package version is proven to provide the required binary.Attack Path
- An attacker compromises the npm package, a relevant maintainer account, or a transitive dependency used by the unpinned release.
- The attacker publishes a malicious version containing harmful package code or an npm lifecycle script.
- A user installs the skill after that version becomes the version selected by npm dependency resolution.
- The installer retrieves the malicious package because no exact version or integrity hash constrains resolution.
- Package-controlled code executes during installation or is loaded later by the runtime.
- The malicious code operates with the privileges and environment access of the process performing installation or execution.
Impact Assessment
Successful exploitation could permit arbitrary code execution under the account installing or running the dependency. The resulting scope may include access to files, environmen ...[truncated 307 chars]

Remediation Suggestions
- Pin
axiosto an exact, reviewed version rather than relying on the registry's current resolution. - Commit and enforce a lockfile containing resolved versions and package integrity hashes.
- Verify package provenance and integrity through a trusted registry and appropriate npm security controls.
- Disable npm lifecycle scripts during installation where package functionality permits, for example by using
--ignore-scripts. - Review and pin all transitive dependencies through the lockfile, and perform automated dependency and provenance scanning.
- Remove
bins: ["axios"]unless a verified executable is genuinely required and supplied by the pinned package. - Perform dependency installation with a least-privileged account and avoid exposing unrelated credentials or sensitive environment variables to the installer.
