Summary

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.

Risk Assessment

Organizations using Tauri with script-src directives containing data: or blob: are exposed to arbitrary JavaScript execution by attackers, potentially leading to application compromise and data leakage.

Recommendation

Remove data: and blob: sources from the script-src directive in the Tauri application's CSP and use only trusted script sources.
