Security audit

Luma

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent Luma read connector, but its fallback setup asks users to run an unverified remote installer, so it needs review before installation.

Review the oo CLI installation path before using this skill. Prefer installing the CLI through a verified package or manually downloading and inspecting a pinned installer with a published checksum or signature. Only connect Luma if you are comfortable letting OOMOL-mediated commands read your Luma calendar, event, guest, and profile data.

Vulnerability Patterns

Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
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
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

High

Category: Supply Chain
Confidence: 98% confidence
Finding: The skill instructs users to install the CLI via a shell pipeline that downloads a remote script and executes it immediately (curl ... | bash). This creates a supply-chain and remote-code-execution risk: if the install endpoint, transport, DNS, or hosting is compromised, arbitrary code runs on the user's machine with the user's privileges.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The description instructs use of the skill for "ANY Luma request," a very broad activation condition that does not define scope limits or exclusions. This can cause unintended invocation whenever Luma is mentioned, rather than only for specific supported actions or contexts.
