CVE-2026-42184
HighCVSS 8.8Summary
Tauri to framework do budowania binariów dla wszystkich głównych platform desktopowych. W wersjach od 2.0 do 2.11.0 występuje błąd w funkcji is_local_url(), który błędnie klasyfikuje zdalne adresy URL jako zaufane lokalne źródła na systemach Windows i Android.
Risk Assessment
Atakujący może wykorzystać tę podatność, hostując stronę na domenie, której subdomena odpowiada niestandardowemu schematowi aplikacji, co może prowadzić do nieautoryzowanego dostępu do danych użytkowników.
Recommendation
Zaleca się aktualizację do wersji 2.10.3 lub nowszej, aby usunąć tę podatność.

Original NVD description (English source)
Tauri is a framework for building binaries for all major desktop platforms. From 2.0 to 2.11.0, a flaw in Tauri's is_local_url() function causes it to incorrectly classify remote URLs as trusted local origins on Windows and Android. On these systems, Tauri maps custom URI scheme protocols to http://<scheme>.localhost/ because those platforms' WebView implementations cannot serve custom URI schemes directly. The issue is that Tauri's check to see if the origin is local, only checks the first subdomain of the URL. An attacker can abuse this by hosting a page on a domain whose subdomain matches the custom scheme of the application. This vulnerability is fixed in 2.10.3.
