Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The MStore API plugin for WordPress, prior to version 3.9.8, contains a blind SQL injection vulnerability caused by missing sanitization and escaping of a user-supplied parameter that is concatenated directly into a SQL query. The flaw is present only when the site has purchased and enabled the plugin's pro features and is also running the WooCommerce Appointments extension.
Unauthenticated attackers can supply crafted input over the network to trigger the injection. Successful exploitation grants full read, write, and delete access to the database, corresponding to the CVSS 9.8 rating that reflects no authentication, no user interaction, and complete confidentiality, integrity, and availability impact.
Public advisories published by WPScan on 10 July 2023 identify the issue and direct administrators to upgrade the MStore API plugin to version 3.9.8 or later to eliminate the vulnerable code path.
The EPSS score for this CVE rose from a low baseline to a peak of 0.7441 (current value 0.6078), indicating that exploitation interest increased measurably after disclosure.
