Cyr to Lat <= 3.5 - Authenticated SQL Injection

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVE CVE-2022-4290
CVSS 8.8 (High)
Publicly Published April 13, 2023
Last Updated April 13, 2023
Researcher Ramuel Gall - Wordfence


The Cyr to Lat plugin for WordPress is vulnerable to authenticated SQL Injection via the 'ctl_sanitize_title' function in versions up to, and including, 3.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This potentially allows authenticated users with the ability to add or modify terms or tags to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. A partial patch became available in version 3.6 and the issue was fully patched in version 3.7.

Wordfence blocked 6,161 attacks targeting this vulnerability in the past 24 hours.
