CVE-2026-68951Network attack vectorHinoki check available

Unauthenticated bookmark disclosure via missing access checks

Published Aug 31, 2026 · Updated Aug 31, 2026

Incorrect authorization in GROWI 8.0.0 and earlier allows remote attackers to retrieve other users' bookmark data over the network. The bookmark-listing API returns entries without applying each page's view permission or the administrator's page-list visibility setting. Unauthenticated reachability requires guest viewing to be enabled; the bounded impact is disclosure of paths and titles for pages the guest cannot view.
