- Unpinned Third-Party Package Installation## Vulnerability Details **File Location**: `SKILL.md`, lines 89–90 **Vulnerability Type**: Unpinned and unverified third-party dependencies **Risk Level**: Medium ```bash npx clawhub install a-stock-daily-express pip install akshare ``` ### Technical Analysis The documented installation process resolves mutable package versions at installation time. It does not specify reviewed versions, lockfiles, package hashes, or other integrity constraints. The `pip install akshare` command installs the latest package version and its transitive dependencies available from the configured Python package index. Likewise, `npx` may retrieve and execute package tooling dynamically. Consequently, the code ultimately installed can differ from the code that was originally reviewed. This creates a supply-chain exposure if a package publisher account, registry artifact, transitive dependency, or package-resolution source is compromised. The finding does not establish that either named package is currently malicious; the weakness is the absence of version and integrity controls. ### Attack Path 1. An attacker compromises a referenced package, one of its transitive dependencies, its publisher account, or the package source used by the victim. 2. The attacker publishes a malicious release that remains compatible with the unconstrained installation command. 3. A user follows the installation instructions and runs the unpinned command. 4. The package manager resolves and downloads the attacker-controlled release. 5. Malicious installation hooks or subsequently imported package code execute in the user's environment. ### Impact Assessment Successful exploitation could execute arbitrary code with the privileges of the user performing the installation or running the Skill. Depending on those privileges and the environment, this could permit access to user-readable files, modification of project or environment data, theft of accessible credentia ...[truncated 273 chars]
- Remediation
- ## Remediation Suggestions - Pin every direct dependency to a reviewed, exact version. - Record transitive dependency versions in committed lockfiles. - For Python dependencies, use a requirements file containing cryptographic hashes and install with `pip install --require-hashes -r requirements.txt`. - Use a controlled package index or explicitly document the expected trusted registry. - Replace ephemeral `npx` execution with a verified, pinned local installation where possible. - Run installation and report generation as an unprivileged user in an isolated environment. - Add automated dependency vulnerability and provenance checks to the release process. - Review and deliberately update dependency pins rather than resolving unrestricted latest releases during installation.
