Summary

Penpot before 2.18.0 has a missing authorization flaw (CWE-862) in the unauthenticated get-view-only-bundle RPC, which returns every share-link row for a file. A holder of one restrictive share link can read other links' secret IDs, page scopes and permissions, then replay a more permissive token to access page data outside the original share. An attacker needs only one scoped share link, and the impact is limited to confidentiality.

Description from the CNA

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.
