Summary

CVE-2023-3197 is a critical-severity SQL Injection (CWE-89) vulnerability in Inspireui Mstore Api. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 3.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

The MStore API plugin for WordPress is vulnerable to unauthenticated blind SQL injection via the 'id' parameter in versions up to and including 4.0.1. The flaw stems from insufficient escaping of user-supplied input and inadequate preparation of SQL queries, allowing attackers to inject additional clauses into existing database statements. The issue is tracked as CWE-89 and carries a CVSS 3.1 score of 9.8.

Unauthenticated remote attackers can exploit the vulnerability over the network without any credentials or user interaction. Successful exploitation enables extraction of sensitive database contents and, given the high impact metrics, may also permit modification or deletion of data, resulting in full compromise of the confidentiality, integrity, and availability of the affected WordPress site.

The referenced Wordfence advisory and WordPress plugin changeset 2929891 indicate that the vendor addressed the issue by updating the affected helper file in the MStore API repository; site administrators should apply the patched version beyond 4.0.1. The EPSS score reached a peak of 0.3996 after disclosure before settling at the current value of 0.2957.
