CVE-2026-105684 · Severity: medium · CVSS 4.3 · Published 2026-10-05

Penpot is an open-source design and prototyping platform that allows users to share files via page-scoped share links for collaboration. Prior to version 2.18.0, the platform's comment query functions did not properly restrict access to shared pages, allowing a holder of a page-scoped share link to retrieve comment threads and full comment content from other pages in the same file, including commenter names, email addresses, and photos. The exposed page identifiers could also be used to access unshared design content through other affected functionality.
