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: 0.70). The skill's SKILL.md requires calling Amplitude tool endpoints (e.g., AMPLITUDE_LIST_COHORTS, AMPLITUDE_GET_EVENT_CATEGORIES, AMPLITUDE_FIND_USER) to fetch event categories, cohort lists, and user data from an external Amplitude connection, and those user-generated/untrusted fields are read and used to select IDs and drive subsequent actions (e.g., choosing cohort_id or validating event_type), so third-party content can materially influence 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: 0.90). The skill explicitly requires connecting at runtime to the MCP endpoint https://rube.app/mcp and instructs to call RUBE_SEARCH_TOOLS to fetch current tool schemas that directly determine the agent's available tools/instructions, making this external URL a required runtime dependency that controls agent behavior.
