This vulnerability is caused by improper neutralization of special characters in an SQL command, allowing blind SQL injection. An attacker could read or modify the content of the WordPress database, leading to confidentiality breaches and potential integrity damage. The weakness is a classic SQL Injection (CWE-89).

The WordPress Automotive Listings plugin supplied by themesuite is affected for all versions up to and including 18.6. Users running these versions should verify the plugin version and consider upgrading. The vulnerability does not affect other WordPress components directly.

The CVSS score of 9.3 indicates high severity, and the EPSS score of less than 1% suggests a low, but not negligible, likelihood of exploitation in the wild. The vulnerability has not been listed in the CISA KEV catalog. Because it is a blind SQL injection that operates through the plugin’s web interface, the attack vector is from an external user with web access, likely without authentication. No special environment is required, so the window of opportunity is broad, but lack of immediate exploitation feedback means detection may be difficult.
