- Unpinned Remote Package and Repository Installation## Vulnerability Details **File Location**: `SKILL.md:123-131` **Vulnerability Type**: Unpinned remote dependency installation **Risk Level**: Medium ### Vulnerable Code ```bash pip install openpaw ``` ```bash git clone https://github.com/jcools1977/Openpaw-.git cd Openpaw- pip install -e . ``` ### Technical Analysis The installation instructions retrieve and install mutable remote content without pinning a specific package version, source commit, or artifact hash. `pip install openpaw` resolves whichever package release the package index currently serves. The documentation does not cryptographically bind that package to the audited source tree. The Git-based alternative clones the repository's current default branch rather than a reviewed commit. Consequently, the code installed by a user may differ from the code covered by this audit. Python package installation can invoke build-backend logic. If the package-index account, repository, publishing workflow, or upstream source is compromised, modified build or package code could execute with the privileges of the user performing the installation. This finding concerns the documented supply-chain process. The audited local implementation itself contained no malicious runtime code, network requests, command execution, credential access, persistence, or data-exfiltration behavior. ### Attack Path 1. An attacker compromises the package-index publisher account, source repository, release workflow, or another relevant upstream distribution channel. 2. The attacker publishes a malicious package release or modifies the repository's default branch. 3. A user follows one of the unpinned installation commands in `SKILL.md`. 4. `pip` downloads and builds the current attacker-controlled content rather than a specifically reviewed artifact. 5. Malicious build or runtime code executes under the installing user's account. ### Impact Assessment Successful exploitation could allow arbitrary code execution with the p ...[truncated 536 chars]
- Remediation
- ## Remediation Suggestions 1. Pin the package to a reviewed release instead of installing an unconstrained latest version: ```bash pip install openpaw==0.1.0 ``` 2. Publish and document trusted SHA-256 hashes, then require hash verification: ```text openpaw==0.1.0 --hash=sha256:<verified-release-hash> ``` Install through a requirements file with: ```bash pip install --require-hashes -r requirements.txt ``` 3. Pin Git installations to a full, reviewed commit SHA: ```bash git clone https://github.com/jcools1977/Openpaw-.git cd Openpaw- git checkout <full-reviewed-commit-sha> pip install -e . ``` 4. Verify signed tags, commits, and release provenance before installation. Protect publishing accounts and CI workflows with multi-factor authentication and least-privilege credentials. 5. Build reproducible release artifacts in a controlled CI environment, publish checksums or attestations, and explicitly identify which release corresponds to the audited source. 6. Perform installation in an isolated virtual environment and avoid running package installation with administrative privileges.
