2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.80). This skill's workflow includes explicit commands that fetch and execute public web content (e.g., sub-skills/11-installation.md: "curl -fsSL https://bun.sh/install | bash", and sub-skills/31-installing-packages.md: bun add from GitHub or external registries), which clearly ingests untrusted third-party content that can materially change runtime behavior.
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Potentially malicious external URL detected (high risk: 1.00). The skill contains installation commands that fetch and immediately execute remote scripts from https://bun.sh/install (and bun.sh/install.ps1 via PowerShell), which run remote code at runtime and are presented as a required step to install Bun for using this skill.
