Vulnerability Type: Unpinned dependency installation from a mutable package repository
Risk Level: MediumVulnerable Code
yaml - id: uv-pip kind: shell command: "pip install uv" label: "Install uv via pip (alternative)"Technical Analysis
The installation command retrieves and installs the latest available release of the
uvpackage without specifying an audited version or validating a cryptographic hash. Consequently, the code executed during installation depends on mutable third-party package repository state rather than an immutable, previously reviewed artifact.Python package installation may execute package-controlled build or installation logic. If the package, maintainer account, release process, or distribution channel is compromised, a malicious release could run code under the privileges of the user invoking the installation command.
This finding does not establish that the current
uvpackage is malicious. The vulnerability is the absence of version pinning and artifact integrity verification in the supplied installation instruction.Attack Path
- An attacker compromises the upstream package, a maintainer account, or the package publication pipeline.
- The attacker publishes a malicious or backdoored release under the expected package name.
- A user follows the Skill's alternative installation instruction and executes
pip install uv. pipresolves the mutable latest release instead of a known, audited version.- Malicious package installation or build logic executes locally with the invoking user's privileges.
- The payload may access files, environment variables, and credentials available to that user, including Bybit credentials if they are already present in the environment.

Remediation Suggestions
- Pin
uvto a specific version that has been reviewed and tested, for exampleuv==<approved-version>. - Require cryptographic hash validation by using a requirements file with
--require-hashesand the expected SHA-256 hashes for all permitted artifacts. - Document the expected package publisher, repository, version, and artifact hashes through an authenticated project-controlled channel.
- Prefer installation from an immutable, verified release artifact rather than resolving the latest package dynamically.
- Establish a controlled upgrade process that reviews release notes, source changes, signatures, and hashes before changing the pinned version.
- Advise users to install in an isolated environment without sensitive API credentials loaded and without elevated privileges.
