Executive Summary

The Canva Android App before version 2.376.0 allowed a WebView to return headers from an external origin. This means a threat actor controlling the WebView could access a user's session, potentially leading to unauthorized account access or data exposure.

Impact Analysis

If you use the vulnerable Canva Android App version, an attacker could steal your session data, gain access to your Canva account, or perform actions on your behalf without your consent.

Compliance Impact

This vulnerability could potentially violate compliance with GDPR and HIPAA by exposing user session data through unauthorized header access in a WebView. Unauthorized access to session data may lead to data breaches, which are a primary concern under both regulations.

Mitigation Strategies

Update the Canva Android App to version 2.376.0 or later to address the vulnerability.
