Summary

The Tamara Checkout WordPress plugin through 1.9.9.20 does not verify the order key, a nonce, or any capability on its public payment cancel/fail return URLs, changing a WooCommerce order's status based solely on an attacker-supplied numeric order id. An unauthenticated attacker can cancel or fail arbitrary orders store-wide by enumerating ids, triggering downstream stock-release and notification side-effects.

Risk Assessment

An attacker can disrupt store operations by canceling orders and causing unwanted side effects, potentially leading to financial losses and loss of customer trust.

Recommendation

Update the Tamara Checkout plugin to a version newer than 1.9.9.20 or apply available patches.
