Vulnerability description
DayBreach CVE AI Research
CVE-2026-42184 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
