Security audit

R

Security checks for vulnerabilities and agentic risk

Overview

This is a simple R programming guidance skill with no hidden execution, persistence, or data access behavior.

This skill appears safe to install as an R reference. It may lead an agent to give R coding advice and may expect Rscript to exist for R-related workflows, but the artifact does not request sensitive access or perform actions on its own.

Vulnerability Patterns

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

Unbounded Output

Medium

Category: Output Handling
Content: ## Data Frames vs Tibbles - Tibble never converts strings to factors — safer defaults - Tibble never drops dimensions — `df[, 1]` stays tibble - Tibble prints better — shows type, doesn't flood console - `as_tibble()` to convert — from `tibble` or `dplyr` package ## Assignment
Confidence: 80% confidence
Finding: Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.
