TimeCamp

Security checks for vulnerabilities and agentic risk

Overview

The TimeCamp workflow requires approval for changes, but its setup can introduce broader agent changes that the skill does not explain.

Review and install the CLI separately before using this skill. Disable startup skill synchronization if you do not want other agent skills installed or refreshed. Connect only the intended TimeCamp account and retain approval for edits. The remote installer and hosted service remain unverified; the scanner's partial status did not identify missing bundled code.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command contains no TimeCamp interaction and instead executes an installer hosted by Oomol. No connection between that installation and the declared TimeCamp functionality is established, so it cannot be treated as a demonstrated supporting implementation detail. The remote script's contents and further effects are not visible in the supplied chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The setup command executes a remotely fetched, mutable script directly in Bash without first verifying its integrity or reviewing its contents; the PowerShell alternative has the same weakness. If the installation endpoint or distribution infrastructure is compromised, attacker-controlled code runs with the invoking user's permissions and could steal accessible credentials or modify local files. The legitimate dependency and missing-command condition reduce exposure but do not eliminate this supply-chain risk.

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.

- **`OOMOL_INSUFFICIENT_CREDIT`** — OOMOL billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.

- **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.
