CVE-2026-23480
HighSummary
Blinko to projekt notatek kartkowych wspierany przez sztuczną inteligencję. Przed wersją 1.8.4 występowała podatność na eskalację uprawnień w punkcie końcowym upsertUser, która pozwalała na modyfikację haseł innych użytkowników przez zalogowanych użytkowników.
Risk Assessment
Podatność ta może prowadzić do eskalacji uprawnień do superadministratora oraz pełnego przejęcia konta przez dowolnego uwierzytelnionego użytkownika, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację do wersji 1.8.4 lub nowszej, aby usunąć tę podatność oraz wprowadzenie dodatkowych środków zabezpieczających w celu weryfikacji uprawnień użytkowników.

Original NVD description (English source)
Blinko is an AI-powered card note-taking project. Prior to version 1.8.4, there is a privilege escalation vulnerability. The upsertUser endpoint has 3 issues: it is missing superAdminAuthMiddleware, any logged-in user can call it; the originalPassword is an optional parameter and if not provided password verification is skipped; there is no check for input.id === ctx.id (ownership verification). This could result in any authenticated user modifying other users' passwords, direct escalation to superadmin, and complete account takeover. This issue has been patched in version 1.8.4.
