Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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.
The skill’s runtime workflow (Phase 1 Scan Inbox / Phase 3 Extract Signal Snippets) ingests full email body text by fetching new messages from a monitored AgentMail inbox (agentmail.dev) and then scanning/extracting keyword contexts from that free text.
