Official description

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the get-comment-threads, get-comment-thread, and get-comments RPC commands use check-comment-permissions! but do not apply the share link's pages restriction. A holder of a page-scoped share link can retrieve comment threads and full comment bodies from other pages in the same file, including commenter names, email addresses, photos, and page identifiers. The disclosed page identifiers can also be used with affected page-reading functionality to access unshared design content. This issue is fixed in version 2.18.0.
