Autopay vulnerabilities

The Autopay WordPress plugin before 5.0.1 does not enforce the signature on one of its payment callbacks. This allows unauthenticated users to disclose and delete the stored payment parameters of other customers' orders.

Unauthenticated Cross Site Scripting (XSS) vulnerability in Autopay versions up to 5.0.0. An attacker can inject a malicious script that executes in the victim's browser.

The Autopay WordPress plugin before 5.0.1 does not perform any capability or nonce check before saving a styling option from a public request, and does not escape that value when it is later output on the checkout page, allowing unauthenticated attackers to store JavaScript that executes in the browser of any user, including administrators, who loads the checkout page.
