Summary

Penpot before 2.18.0 has a missing authorization check (CWE-862) in the get-page RPC command. The command does not verify that the requested page belongs to the authorized pages of a share link. A holder of a valid share link who also has an authenticated Penpot session can retrieve the full shape and design data of another page in the same file if its identifier is known.

Description from the CNA

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the get-page RPC accepts a share-link permission object with blanket read access but does not verify that the caller-selected page-id belongs to the link's authorized pages set. An attacker with both a valid share link and the attacker's own authenticated Penpot session can retrieve the complete shape and design data of another page in the same file when its identifier is known, because get-page requires authentication. The related get-file-fragment RPC also permits share-link access without mapping fragments to authorized pages. This issue is fixed in version 2.18.0.
