Vulnerability Type: Unpinned third-party dependency
Risk Level: MediumVulnerable Code
python """ 酒店P&L数据可视化脚本 使用ECharts生成交互式图表 依赖：pip install pyecharts """The dependency is subsequently imported as follows:
python try: from pyecharts.charts import Bar, Line, Pie, Gauge, Radar from pyecharts import options as opts from pyecharts.globals import ThemeType HAS_PYECHARTS = TrueTechnical Analysis
The project directs users to install
pyechartswithout specifying a reviewed version, cryptographic hash, lockfile, or trusted package index. Consequently,pipresolves whichever package and transitive dependency versions are available at installation time.This makes the installation non-reproducible and leaves the project exposed to supply-chain compromise. If a future release or transitive dependency is compromised, malicious code could execute during package installation or when
pyechartsis imported. The package name itself is not identified as malicious; the risk arises from uncontrolled dependency resolution.Attack Path
- A user or automated agent follows the documented
pip install pyechartsinstruction. pipcontacts its configured package index and resolves the latest available version and transitive dependencies.- An attacker compromises a resolved release, one of its transitive dependencies, or the configured package source.
- Malicious installation hooks or import-time code execute when the package is installed or imported.
- The payload runs with the privileges of the user or service executing the installation or chart generator.
Impact Assessment
Successful exploitation could execute arbitrary code within the installing user’s security context. Depending on that account’s privileges and environment, the attacker could access files an ...[truncated 416 chars]

Remediation Suggestions
- Create a dependency manifest and pin
pyechartsto a reviewed version:
text pyecharts==<reviewed-version>- Generate and record cryptographic hashes for the package and all transitive dependencies:
text pyecharts==<reviewed-version> \ --hash=sha256:<verified-hash>- Install through a locked requirements file with hash enforcement:
bash python -m pip install --require-hashes -r requirements.txt-
Use an isolated virtual environment and a trusted, explicitly configured package index.
-
Review and update the lockfile through a controlled dependency-update process that includes vulnerability scanning and package provenance verification.
-
Avoid encouraging direct installation of an unconstrained latest version in source-code documentation.
