Vulnerability Type: Unpinned third-party dependency
Risk Level: MediumVulnerable Code
bash **Using venv**: ```bash python -m venv easypaper-env source easypaper-env/bin/activate # On Windows: easypaper-env\Scripts\activate pip install easypaperUsing conda:
bash conda create -n easypaper python=3.11 conda activate easypaper pip install easypaperDirect install (not recommended):
bash pip install easypapertext ### Technical Analysis The installation instructions retrieve the latest package matching the `easypaper` name from the configured Python package index without specifying a reviewed version, lock file, package hash, or signature. Consequently, the code installed by users can change after this skill has been audited. A Python package can execute code during installation, import, or normal SDK use. An isolated virtual environment reduces dependency conflicts but does not sandbox the package from the invoking user's files, environment variables, network access, or operating-system permissions. ### Attack Path 1. An attacker compromises the `easypaper` package, one of its transitive dependencies, its publisher account, or the package-index delivery process. 2. The attacker publishes a malicious release that satisfies the unrestricted package request. 3. A user follows the skill instructions and runs `pip install easypaper`. 4. The package manager installs the malicious release or compromised transitive dependency. 5. Malicious code executes during installation, import, or paper generation with the privileges of the invoking user. ### Impact Assessment Successful exploitation could provide arbitrary code execution under the installing user's account. The accessible scope may include project files, generated papers, metadata, environment variables, user-readable credentials, and ...[truncated 197 chars]- Remediation

Remediation Suggestions
- Pin EasyPaper to a specifically reviewed release rather than installing an unrestricted latest version.
- Maintain a dependency lock file that also pins all transitive dependencies.
- Record and enforce cryptographic package hashes, for example with
pip install --require-hashes -r requirements.txt. - Verify the package publisher and link directly to the expected package and source repositories.
- Review new releases before updating the pinned version and hashes.
- Continue using a virtual environment, but do not describe it as a security sandbox.
- Perform installation and generation as an unprivileged user in a constrained environment when processing untrusted inputs.
