requirements.txt:1-2:text requests python-dotenvSKILL.md:13-15:yaml install: - kind: pip spec: -r requirements.txtTechnical Analysis
The dependency declarations do not constrain package versions or verify package hashes. Each installation can therefore resolve a different release of
requests,python-dotenv, or their transitive dependencies from the configured Python package index.This exceeds the minimum dependency privileges necessary for the Skill because reviewed, reproducible versions could be pinned without affecting its declared veterinary consultation functionality. If a dependency account, package release, package index, or transitive dependency is compromised, installation may retrieve attacker-controlled content that was not present during this audit.
No evidence indicates that the currently named packages are malicious. The vulnerability is the absence of controls that ensure future installations receive the same reviewed artifacts.
Attack Path
- An attacker compromises a declared dependency, one of its transitive dependencies, or the package distribution channel.
- The attacker publishes a malicious version that still satisfies the unconstrained requirement.
- A user or agent installs the Skill using
pip -r requirements.txt. - Package resolution selects and downloads the malicious or compromised release.
- Attacker-controlled code executes during package installation or when the Skill imports the affected package.
- The code inherits the privileges and accessible data of the account running installation or the Skill.
Impact Assessment
Successful exploitation could allow arbitrary Python code execution in the installer or Skill process. Depending on t ...[truncated 552 chars]

Remediation Suggestions
- Pin every direct dependency to a reviewed version, for example:
text requests==<reviewed-version> python-dotenv==<reviewed-version>- Generate a lock file that includes exact versions for all transitive dependencies.
- Require cryptographic hashes during installation, such as with a hash-locked requirements file and
pip install --require-hashes. - Install only from an explicitly trusted package index and disable unintended extra indexes where operationally possible.
- Run dependency vulnerability and provenance checks in CI before publishing the Skill.
- Review and deliberately update dependency pins rather than resolving the newest available versions during deployment.
- Perform installation and execution under a least-privileged account without unnecessary filesystem, credential, or network access.
