Security audit

Bilibili Danmaku

Security checks across malware telemetry and agentic risk

Overview

This skill appears to do what it says: fetch public Bilibili bullet comments and analyze them locally, with ordinary dependency and data-handling cautions.

Install only if you are comfortable running a local Python environment that downloads third-party packages. Use it for public Bilibili videos, choose the output directory deliberately, and review generated comment datasets and reports before sharing them.

Unpinned Dependencies

Low
Category
Supply Chain
Content
jieba>=0.42.1
snownlp>=0.12.3
wordcloud>=1.9.3
pillow>=10.3.0
Confidence
96% confidence
Finding
The dependency is specified with only a lower bound, so future installs may pull newer, unreviewed versions with breaking changes or newly introduced supply-chain risk. In a skill that processes external content, dependency drift reduces reproducibility and can unexpectedly expose the environment to vulnerable releases.

Confidence
96% confidence
Finding
Using an unpinned minimum version for snownlp allows installations to resolve to any later release, which weakens build reproducibility and increases supply-chain exposure. While not an exploit by itself, it makes it easier for vulnerable or compromised versions to enter the environment unnoticed.

Confidence
96% confidence
Finding
An unpinned wordcloud dependency means different environments may install different versions, including ones with undiscovered defects or incompatible behavior. This is a supply-chain hygiene issue that can become security-relevant if transitive or future versions are compromised.

Confidence
97% confidence
Finding
Pillow is a security-sensitive image-processing library, and leaving it unpinned allows later versions to be installed without review. Because this skill generates SVG/word-cloud related outputs and may process text into rendered artifacts, dependency drift in Pillow is more concerning than for a purely passive library.

Finding
The unpinned numpy requirement permits uncontrolled upgrades, creating reproducibility and supply-chain risk. Although numpy is common and often low risk in normal use, allowing arbitrary future versions is still poor security hygiene.
