Vulnerability Details
File Location:
SKILL.md, line 292; repeated in the dependency table at lines 384–386
Vulnerability Type: Unpinned third-party dependency installation
Risk Level: MediumVulnerable code:
bash pip install azure-ai-voicelive aiohttp azure-identityThe same installation approach is repeated in the dependency documentation:
markdown | azure-ai-voicelive | Python SDK | Required | `pip install azure-ai-voicelive` | | aiohttp | Python library | Required | `pip install aiohttp` | | azure-identity | Python library | Required | `pip install azure-identity` |Technical Analysis
The Skill instructs users to install three Python packages without fixed versions or integrity hashes. Consequently, each installation resolves whatever versions are available from the configured package index at that time, including transitive dependencies that were not part of this audit.
Python packages can run package-controlled code during installation or when imported and used. If a package publisher account, release pipeline, package index, or transitive dependency is compromised, a malicious release could execute under the privileges of the user running the installation or the Skill.
The package names are consistent with the declared Azure VoiceLive functionality, and the audited file does not use a suspicious package source or demonstrate dependency confusion or typosquatting. This finding is therefore an insecure dependency-management weakness, not evidence that the named packages are currently malicious.
The flagged Base64 operations are not vulnerabilities. The Skill decodes Azure VoiceLive audio frames before playback and Base64-encodes microphone audio for transmission to the declared Azure service. It does not pass decoded content to
exec,eval, a shell, or another code interpreter, and it does not encode credentials or unrelated files for output.Attack Path

Remediation Suggestions
- Pin every direct dependency to a reviewed version rather than allowing unrestricted latest-version resolution.
- Generate a lockfile that records all transitive dependencies.
- Require cryptographic hashes during installation, for example:
bash pip install --require-hashes -r requirements.txt - Obtain packages only from an explicitly approved package index and disable unintended fallback indexes.
- Install dependencies in a dedicated virtual environment or container under a non-privileged account.
- Avoid exposing Azure keys or broad cloud credentials during dependency installation.
- Prefer managed identities with narrowly scoped Azure roles over reusable API keys.
- Add automated dependency vulnerability, provenance, and update review checks.
- Update all installation examples in
SKILL.md, including lines 292 and 384–386, so users consistently follow the hardened installation process.
