What is CVE-2026-105693?
CVE-2026-105693 is a medium-severity missing authorization vulnerability in penpot, published on 5 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
