CVE-2023-3197Network attack vector

Database information extraction via unprepared id query

Published Jun 24, 2023 · Updated Apr 8, 2026

Blind SQL injection in FluxBuilder MStore API 4.0.1 and earlier allows remote attackers to extract database information via the id parameter. The WCFM vendor helper incorporates the request id into an existing database query without sufficient escaping or parameterized preparation. No authentication is required; crafted requests can infer and extract sensitive information from the WordPress database through blind query behavior.
