=1.0.0 click>=8.0.0 ``` The Skill instructs users to install these dependencies directly: ```bash cd /path/to/byteplus-cdn pip3 install -r reference/requirements.txt ``` ### Technical Analysis Both dependencies use open-ended `>=` constraints. Consequently, installation does not reproduce a specific reviewed dependency set: any future version published under either package name can satisfy the requirements. There is no lock file, hash verification, or upper version bound in the audited project. Package installation can execute package build or installation logic with the privileges of the user running `pip3`. Although no malicious dependency is currently demonstrated by the project files, this configuration creates a supply-chain exposure to compromised future releases and unexpected compatibility or security regressions. ### Attack Path 1. An attacker compromises the package registry account or release process for an allowed dependency, or otherwise causes a malicious future version to be published under the legitimate package name. 2. The malicious version remains compatible with the open-ended `>=` constraint. 3. A user follows `SKILL.md` and runs `pip3 install -r reference/requirements.txt`. 4. `pip` downloads and installs the new, unreviewed release. 5. Malicious build, installation, import-time, or runtime code executes with the installing user's privileges. ### Impact Assessment Successful exploitation could execute arbitrary code with the privileges of the user installing or running the Skill. Depending on those privileges, the attacker could access local files, environment variables, BytePlus credentials, cloud-storage credentials, and network resources available to that user.

click== ``` 2. Generate a lock file containing transitive dependencies. 3. Record and enforce package hashes with `pip --require-hashes`. 4. Install from an explicitly configured trusted package index. 5. Review and test dependency updates before changing the lock file. 6. Use a dedicated virtual environment and avoid installing the Skill as a privileged system user. ]]>
