What is CVE-2026-56330?

The Capgo product prior to version 12.128.2 is vulnerable to an open redirect issue, particularly within the stripe_portal and stripe_checkout endpoints. This vulnerability arises from the acceptance of unvalidated parameters, including callbackUrl, successUrl, and cancelUrl. With the ability to manipulate these parameters, authenticated attackers can create malicious billing URLs that redirect unsuspecting users to domains controlled by the attackers, facilitating phishing attempts and potential credential harvesting. Organizations utilizing affected versions of Capgo should promptly review their configurations and update to the latest version to mitigate this vulnerability.
