Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVSS 7.2 (High)
Publicly Published October 3, 2023
Last Updated January 22, 2024

Description

The Post SMTP plugin for WordPress is vulnerable to time-based SQL Injection via the log_id parameter in versions up to, and including, 2.6.0 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 with administrator-level privileges to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Wordfence blocked 2,725,623 attacks targeting this vulnerability in the past 24 hours.
