What is CVE-2026-56224?

The Capgo console is prone to a vulnerability that allows the acceptance of access tokens and refresh tokens via URL query parameters in versions prior to 12.128.2. This insecure handling of tokens can enable attackers to craft malicious links, leading to unauthorized access to victim accounts without user confirmation. As a result, sensitive tokens may be exposed in browser history and logs, increasing the risk of session hijacking and data compromise.
