ImgBB

Security checks for vulnerabilities and agentic risk

Overview

The ImgBB skill is coherent for uploading images, but its setup instructions include unverified remote installer commands that can execute changing code from the internet.

Use this skill only if you trust OOMOL and the ImgBB connector. Before running first-time setup, prefer an official signed or version-pinned installation path, inspect downloaded installer scripts, and approve any upload payload because uploads create hosted ImgBB content.

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: 97% confidence
Finding: The skill instructs users to install software by piping a remotely fetched script directly into a shell, which creates a supply-chain and remote-code-execution risk if the host, transport, or published installer is compromised. In this context, the command is presented as an operational recovery step inside the skill, increasing the chance that an agent or user will execute it without separately validating the script contents.
