CVE-2025-58656: 
WordPress vulnerability analysis and mitigation

A Use of Hard-coded Credentials vulnerability was discovered in the Estonian Shipping Methods for WooCommerce plugin, identified as CVE-2025-58656. The vulnerability affects versions through 1.7.2 and was disclosed on September 22, 2025. This security issue allows unauthorized access to retrieve embedded sensitive data from the affected WordPress plugin (Patchstack).

The vulnerability has been assigned a CVSS v3.1 base score of 5.3 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. It is classified under CWE-798 (Use of Hard-coded Credentials) and requires no authentication to exploit. The technical assessment indicates that the vulnerability allows for sensitive data exposure through embedded credentials (NVD, Patchstack).

The vulnerability could enable malicious actors to access sensitive information that is normally restricted from regular users. This exposure of sensitive data could potentially be leveraged to exploit other weaknesses in the system (Patchstack).

As no official fix is currently available and the software appears to be abandoned (last updated over a year ago), the recommended mitigation strategy is to remove and replace the plugin with an alternative solution. It's noted that merely deactivating the software does not remove the security threat unless a virtual patch is deployed (Patchstack).
