Signalbase

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent read-only Signalbase connector, but its fallback setup tells users to execute unverified remote installer scripts.

Install only if you trust OOMOL's CLI distribution path, and prefer a verified or package-manager installation method instead of running the pasted remote installer commands directly. Normal Signalbase reads appear scoped, but first-time setup can modify your machine with your user privileges.

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 the CLI by piping a remotely fetched script directly into a shell, which is a classic supply-chain and remote-code-execution risk. If the install endpoint, transport path, or hosting account were compromised, arbitrary code would execute immediately on the user's machine with the user's privileges.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The description says to use this skill for "ANY Signalbase request" and "Whenever a task involves Signalbase," which is very broad and lacks boundaries or exclusion conditions. This can cause unintended invocation for casual mentions or tasks only tangentially related to Signalbase.
