  • The boundary between what a workspace grant permits and what the server will actually do, on the write side as much as the read side, since an attacker able to create or edit pages can seed content the next agent to read the workspace will treat as instruction

    Covered by Sorona

No target matches. Try part of a host name, such as the company name.

Out of scope 7

Don't test these. A program can exclude a host another program covers; the program you report to decides.

  • Attacks against Notion's users or against its physical property

    Sorona

  • CSRF on unauthenticated forms, rate-limiting issues, and banner or version disclosure

    Sorona

  • Prompt engineering for inappropriate AI responses, which the policy places out of scope in as many words

    Sorona

  • Self-XSS, and clickjacking without a working exploit behind it

    Sorona

  • The MCP clients on the other end. Claude, Cursor, VS Code and the rest are other vendors' software, so a defect that lives in the client rather than in Notion's server belongs with its maintainer

    Sorona

  • The presence of robots.txt or .well-known files, which is expected rather than a finding

    Sorona

  • Use of automated scanning tools, and the output they produce without a demonstrated exploit

    Notion through 3.1.0 on macOS might allow code execution because of RunAsNode and enableNodeClilnspectArguments.
