CoderPad

Security checks for vulnerabilities and agentic risk

Overview

The CoderPad integration is coherent, but its setup can execute downloaded code without separate approval and may introduce undisclosed changes to installed agent skills.

Review and approve CLI installation separately, using a verified, fixed version. Check and control automatic skill synchronization before running it. Connecting CoderPad also entrusts OOMOL with credential-backed access to interview and organization data. Keep the required confirmations for data changes. External installer contents and runtime behavior remain unverified; the artifacts do not establish malicious intent.

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

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command does not interact with CoderPad. It executes an installer from cli.oomol.com, with no evidence that this installation supports the declared CoderPad functionality. The installer's contents are not supplied, so its further behavior cannot be assessed.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
85% confidence
Finding

The supplied chunk's sole behavior is a generic CLI login, rather than CoderPad data access or management. Authentication could be a supporting implementation detail, but nothing in this chunk establishes that oo auth login supports CoderPad. The mismatch concerns the apparent primary purpose, not any demonstrated data theft or other malicious behavior.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable HTTPS installer directly into bash executes remote content without a pinned version, integrity verification, or an opportunity to inspect the downloaded artifact. A compromised distribution endpoint could execute arbitrary code as the local user; the relevant dependency and conditional fallback reduce exposure but do not remove this supply-chain risk.

First-time setup executes downloaded installation scripts without warning about local system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The missing-CLI fallback instructs the agent to execute downloaded shell or PowerShell code without explicit approval for installation or disclosure of local system changes. Although installing this dependency is relevant to CoderPad access, a routine request could thereby lead to execution of compromised installer code with the invoking user's privileges.

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.
