CVE-2026-18752
Last modified
CVE-2026-18752 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. The Persistent Login plugin for WordPress is vulnerable to generic SQL Injection via 'wppl_device_id' Cookie in all versions up to, and including, 3.1.0 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 subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. EPSS estimates a 0.25% chance of exploitation in the next 30 days.

This vulnerability is only exploitable when the plugin's Login History feature is enabled.
