Users should avoid using the affected version 1.1.6 or earlier until a fix is released. Monitor vendor advisories for updates. As the plugin is not a cloud service, remediation depends on applying vendor patches once available.
Description
CVE-2026-103359 is a vulnerability in the PayDunya WooCommerce Payment Gateway WordPress plugin up to version 1.1.6. The plugin fails to verify the authenticity of incoming payment notifications properly. Until the gateway is configured, it uses a value derived from an empty secret for authentication, which can be computed by anyone. This flaw allows unauthenticated attackers to mark arbitrary WooCommerce orders as paid and completed without authorization.
