Fireflies

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent Fireflies connector, but its setup instructions tell the agent to run remote installer scripts directly in a shell if the CLI is missing.

Install only if you trust OOMOL's CLI distribution path, and prefer a verified/manual install method over the embedded one-line remote shell commands. Before using it, confirm exact targets for transcript deletion, role changes, privacy changes, and other Fireflies write actions.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill recommends installing the CLI by piping a remotely fetched script directly into bash, which creates a classic supply-chain and remote code execution risk. If the install endpoint, transport path, or hosting account were compromised, a user following this instruction could execute arbitrary code on their machine.

Finding

The description says to use this skill for "ANY Fireflies request," including all read, write, and delete operations. That activation scope is extremely broad and lacks constraints or negative examples, which can cause unintended invocation for loosely related mentions of Fireflies.
