Chargeblast

Security checks for vulnerabilities and agentic risk

Overview

Chargeblast actions have clear safeguards, but setup can execute unverified remote code and make broader agent changes without clear user approval.

Review the setup before installing. Install a verified CLI release yourself, approve its local changes, and review or disable automatic agent-skill synchronization. Connecting Chargeblast gives OOMOL access to the connected account; keep permissions limited and retain confirmation for credit requests and alert updates. The remote installer and hosted 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
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied code installs or bootstraps software from Oomol rather than interacting with Chargeblast. No connection establishing this as a supporting Chargeblast implementation detail is provided. The downloaded script's contents are unavailable, so its additional behavior cannot be determined.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable HTTPS download directly into bash executes whatever the installation endpoint returns with the invoking user's privileges, without first checking its integrity or contents. The endpoint is relevant to the documented CLI dependency, but compromise of its delivery infrastructure could expose local files, credentials, and account access; the PowerShell alternative has the same underlying risk.

Content

The setup workflow executes downloaded installation scripts without warning about remote code execution or local system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

When the CLI is missing, the workflow directs installation through remotely downloaded shell or PowerShell code without an explicit approval checkpoint or explanation of local changes. Conditional setup reduces exposure, but a Chargeblast data request can still lead to local code execution beyond the user's apparent task scope.

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.
