Roam SCIM

Security checks for vulnerabilities and agentic risk

Overview

Account changes require approval, but the CLI setup can introduce persistent changes to your agents that the skill does not explain.

Review the CLI installation separately before proceeding, including its automatic installation of additional agent skills. If you only want this connector, disable startup skill synchronization using the publisher's documented OO_SKILLS_SYNC_DISABLED setting before invoking the CLI: [command reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md#environment-variables). Use limited account permissions and retain the required approvals for changes. The complete bundled artifact was inspected, but downloaded installers and hosted connector behavior remain unverified.

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
97% confidence
Finding

The supplied code performs remote installer execution rather than any visible Roam SCIM operation. Although installation can be a supporting implementation detail, nothing in this chunk establishes that the Oomol installer supports the declared functionality. The remote script's contents and further effects are not available for assessment.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS download directly into bash executes mutable remote content without verifying its integrity or allowing inspection first. The vendor-hosted URL and conditional setup context support a legitimate intent, but compromise of the hosting or release infrastructure could lead to arbitrary code execution with the user's privileges.

Content

Scanner excerpt · SKILL.md (reported line 67)May include surrounding context.

The setup workflow executes downloaded installation scripts without warning about running remote code on the user's system.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The fallback setup directs execution of downloaded shell or PowerShell code without an integrity check or explicit approval for installing software. Although this is a legitimate dependency setup step and only occurs when the CLI is absent, a compromised installer could execute arbitrary code with the invoking user's permissions; server-side API credential handling does not protect local files or credentials.

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.
