Canny

Security checks for vulnerabilities and agentic risk

Overview

This Canny connector skill is mostly coherent, but its setup guidance tells the agent to install a required CLI by executing a remote script directly from the network.

Review the OOMOL oo CLI installer before running it, prefer a verified package or checksum-backed install path if available, and only connect a Canny workspace where you are comfortable allowing read and confirmed write actions through the OOMOL connector.

  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

Finding

The skill recommends installing the CLI via a remote script piped directly into the shell (curl ... | bash), which executes unverified code from the network without integrity checking or review. If the distribution endpoint, DNS, TLS trust chain, or hosting account is compromised, an attacker could achieve arbitrary code execution on the user's machine.

Finding

The description says to use this skill for "ANY Canny request" and "Whenever a task involves Canny," which is an extremely broad activation condition. It does not provide narrower trigger scope, exclusions, or negative examples, so ordinary mentions of Canny-related work could invoke the skill unintentionally.
