notion-sync

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Notion sync tool that can read, write, and update Notion content, with no evidence of hidden or unrelated behavior.

Install only if you are comfortable granting a Notion integration token access to the pages and databases you share with it. Use a least-privilege Notion integration, store NOTION_API_KEY only in a secret manager, prefer dry runs before batch updates, review filters carefully, and enable scheduled monitoring only when you intentionally want ongoing checks.

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

Tool Parameter Abuse

High

Category: Tool Misuse
Confidence: 65% confidence
Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

### Security - Replaces the unbounded `--allow-unsafe-paths` workspace bypass with exact, mode-specific `--allow-read-path` and `--allow-write-path` authorization. - Canonically matches each authorized path so access does not extend to sibling paths or cross from write permission to read permission.

Session Persistence

Medium

Category: Rogue Agent
Confidence: 60% confidence
Finding: Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

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.
Content: Scanner excerpt · SKILL.md (reported line 73)May include surrounding context.
md
- `allowedHosts: ["api.notion.com"]` - a one-line reason explaining that notion-sync needs Notion API access 3. If the request is skipped or unavailable, stop and report the blocker. Never ask the user to paste the token into chat or a command. 4. Run scripts with Gateway-hosted exec. Do not override, expand, inspect, log, or print `NOTION_API_KEY`; OpenClaw injects an opaque sentinel and replaces it only for allowed HTTPS requests to `api.notion.com`.
