Vulnerability Type: Supply-chain risk caused by an unpinned third-party dependency
Risk Level: MediumVulnerable Code
bash pip install funasrTechnical Analysis
The installation instructions retrieve and install the latest available
funasrpackage and its transitive dependencies without version constraints, cryptographic hashes, a lockfile, or a reviewed source reference. As a result, the code installed can change after this skill has been audited.Because Python packages may execute code during installation, import, or normal use, a compromised package release or transitive dependency could run attacker-controlled code. The project itself contains only documentation and no bundled malicious script was identified; the risk arises from unsafe dependency acquisition.
Attack Path
- An attacker compromises the
funasrpackage distribution channel, a maintainer account, or one of its transitive dependencies. - The attacker publishes a malicious version that remains compatible with the unpinned installation command.
- A user follows the documented setup procedure and runs
pip install funasr. pipresolves and installs the attacker-controlled release or dependency.- Malicious code executes during installation, import, or subsequent speech-recognition use with the privileges of the user running Python.
Impact Assessment
Successful exploitation could allow arbitrary code execution under the installing or runtime user's account. Depending on that account's permissions, the attacker could access local files and processed video or audio data, steal accessible credentials, alter environment packages, or perform network operations. The project does not request administrative privileges, so privilege escalation beyond the invoking user's permissions is not established.

Remediation Suggestions
- Pin
funasrand all transitive dependencies to versions that have been reviewed and tested. - Generate and commit a dependency lock or requirements file containing cryptographic hashes.
- Install with hash verification, for example:
bash python -m pip install --require-hashes -r requirements.txt- Explicitly configure and document the trusted package index rather than relying on implicit package-source configuration.
- Regularly scan locked dependencies for known vulnerabilities and review updates before changing pinned versions.
- Recommend installation in an isolated virtual or Conda environment with only the permissions needed for local media processing.
