CVE-2026-95626

Pending analysis
Type:
CWE-79 Cross-Site Scripting (XSS)
Publication date:

Description

Tauri's Content Security Policy hardening, which injects a random nonce to restrict script execution, provides zero protection when an application includes data: or blob: in its script-src directive. Per the CSP Level 3 specification, these scheme sources remain active even when a nonce is present, allowing arbitrary script execution without knowing the nonce.
