High CVSS 7.5
CVE-2026-12493
The Clover Payment Gateway by Zaytech for WooCommerce WordPress plugin before 1.3.6 does not verify that an approved external payment record actually belongs to the WooCommerce order being completed, nor that the paid amount matches the order total, allowing unauthenticated users to mark arbitrary orders as paid by replaying a single genuinely-approved payment reference (for example one obtained from their own minimal purchase).
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can modify or destroy data.
- Weakness
- The authentication mechanism can be bypassed, letting an attacker pose as a legitimate user.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
What to doFold into the next patch cycle. Start with the instances exposed to the internet.
