CVE-2023-36529Network attack vector

SQL injection via undisclosed request handling

Published Nov 3, 2023 · Updated Apr 28, 2026

SQL injection in Favethemes Houzez CRM 1.3.4 and earlier allows remote authenticated users to execute arbitrary SQL via network requests. Published materials do not identify the request parameter, PHP function, database query, or faulty data-handling operation that enables the injection. Patchstack's assessment requires low privileges, while NIST and CISA rate the issue unauthenticated; successful injection can read, change, or delete database data.
