Teamcamp

Security checks for vulnerabilities and agentic risk

Overview

The Teamcamp features are clearly scoped, but setup can execute downloaded software without a clear user approval step.

Review and install the oo CLI separately before enabling this skill, and require approval for any installer execution. OOMOL will mediate access to your connected Teamcamp account; task comments require confirmation. The external installer contents and their full local effects 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
94% confidence
Finding

The visible behavior accesses an Oomol installer endpoint and executes its response, rather than interacting with Teamcamp. Although installing a dependency can be a supporting implementation detail, the supplied content establishes no such relationship here. The downloaded script is not provided, 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 remotely downloaded script directly into Bash executes mutable external content without reviewing it or independently verifying its integrity; the PowerShell alternative has the same issue. If the installer distribution is compromised, it can execute attacker-controlled commands with the agent's local privileges, potentially exposing files and credentials. The legitimate dependency and conditional fallback explain the purpose but do not eliminate the supply-chain risk.

Fallback setup executes remotely downloaded installation scripts without warning the user about the system changes or execution risk.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The fallback directs the agent to install software when the CLI is missing without requiring disclosure or explicit approval for local system changes. Although conditional setup reduces exposure, authorization to perform a Teamcamp operation does not necessarily authorize executing an installer on the user's machine.

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.

- **HTTP 402 without `OOMOL_INSUFFICIENT_CREDIT`** — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
