WP Fastest Cache < 0.9.5 - Authenticated (Subscriber+) SQL Injection

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVE CVE-2021-24869
CVSS 8.8 (High)
Publicly Published October 14, 2021

Researcher Marc-Alexandre Montpas


The WP Fastest Cache plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter in versions before 0.9.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers subscriber-level privileges or above to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
