CVE-2021-24143Public exploitNetwork attack vector

Authenticated SQL injection via unsanitized widget attribute

Published Mar 18, 2021 · Updated Aug 3, 2024

SQL injection in AccessPress Social Icons before 1.8.1 allows remote authenticated users with post permission to execute SQL commands. The aps-social shortcode passes its attacker-controlled id widget attribute into a database query without sanitization, permitting appended SQL such as a time-delay expression. Author-level access is sufficient, and successful injection can read or alter WordPress database data within the database account's privileges.
