CVE-2023-43979Network attack vector

Unauthenticated SQL injection via unescaped blog tag

Published Nov 15, 2023 · Updated Aug 29, 2024

SQL injection in PrestaHero ybc_blog before 4.4.0 allows remote attackers to read, alter, or delete database data via HTTP requests. Ybc_blogBlogModuleFrontController::getPosts() inserts the decoded tag parameter directly into an SQL subquery without pSQL escaping. Guest access is sufficient, exposing shop records and settings to disclosure or modification and enabling administrative takeover.
