Opsgenie

Security checks for vulnerabilities and agentic risk

Overview

Opsgenie changes require approval, but first-time setup can execute an unverified remote installer without asking first.

Review the setup path before enabling this skill. Install a verified, fixed CLI release yourself and check its automatic skill-synchronization settings. OOMOL mediates Opsgenie access; the remote installers and server-side implementation were not verified.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied code installs software from an Oomol endpoint rather than performing an Opsgenie operation. Nothing in the supplied chunk establishes this installation as a supporting dependency for the declared purpose. The remote script's contents are not supplied, so its further behavior cannot be assessed.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a downloaded script directly into Bash executes mutable remote content with the agent process's local privileges, without a pinned version or independent integrity verification. HTTPS protects transport but does not prevent a compromised distribution endpoint from delivering malicious code; the missing-CLI condition limits when this occurs, not its potential impact, and the PowerShell example has the same issue.

Fallback setup executes downloaded installation scripts without warning about local system changes.

Medium
Category
Output Handling
Confidence
91% confidence
Finding

The fallback directs the agent to install software when the CLI is missing without requiring approval for executing an installer or changing the local environment. Restricting this to a command-not-found error reduces exposure, but a request to operate Opsgenie does not inherently authorize local software installation; the write-confirmation rules only explicitly cover Opsgenie state.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
