{"cve":"CVE-2026-42184","nvd":{"published":"2026-05-27T15:16:27.560","modified":"2026-10-26T11:10:00.157","status":"Analyzed","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N","score":6.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-918"],"references":["https://github.com/tauri-apps/tauri/security/advisories/GHSA-7gmj-67g7-phm9","https://github.com/tauri-apps/tauri/security/advisories/GHSA-7gmj-67g7-phm9"],"products":["tauri:tauri"],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-42184","score":0.00312,"percentile":0.23847,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-7gmj-67g7-phm9","url":"https://osv.dev/vulnerability/GHSA-7gmj-67g7-phm9","summary":"Tauri has an Origin Confusion Issue that Allows Remote Pages to Invoke Local-Only IPC Commands","modified":"2026-06-08T23:45:13.347992477Z","packages":[{"ecosystem":"crates.io","name":"tauri","purl":"pkg:cargo/tauri","ranges":[">=2.0.0 <2.11.1"],"fixed":["2.11.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
