    "title": "Penpot: Anonymous share-link token disclosure & page-scope bypass via get-view-only-bundle",
    "summary": "Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the unauthenticated get-view-only-bundle RPC returns every share-link row for a file even when the caller authenticated with only one scoped share link. A holder of a restrictive link can obtain other links' secret IDs, page scopes, comment permissions, and inspection permissions, then replay a more permissive token to access page data that was not included in the original share. This issue is fixed in version 2.18.0.",
