CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N

Description

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, so an unauthenticated attacker can cancel or fail arbitrary orders store-wide by enumerating ids (triggering downstream stock-release and notification side-effects).

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown Tamara Checkout — Up to and including 1.9.9.20
