This is due to an unsafe subquery-detection branch in the Query::parse_key_compare_field() method that, when the user-supplied value matches the regex ^[(\\s]*SELECT\\s+, wraps the value in parentheses and embeds it directly into the SQL string without any escaping or quoting. While the normal LIKE code path correctly uses esc_sql($wpdb->esc_like(...)) and wraps the value in single quotes, this branch completely bypasses those protections. Because the attack payload (SELECT ...) contains no single quotes, WordPress's wp_magic_quotes() provides no protection. This makes it possible for authenticated attackers with administrator-level access to inject arbitrary SQL subqueries — including time-based blind payloads — that can be used to extract sensitive information from the database."}],"title":"WP Optimizer <= 2.5.0 - Authenticated (Administrator+) SQL Injection via 's' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4da302ab-8a5d-481b-8b28-a798e0982893?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimizer/trunk/vendors/wps-framework/Query.class.php#L455"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimizer/tags/2.3.8/vendors/wps-framework/Query.class.php#L455"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimizer/trunk/modules/supporters/activity-log/ActivityLog_Table.class.php#L343"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimizer/tags/2.3.8/modules/supporters/activity-log/ActivityLog_Table.class.php#L343"},{"url":"https://plugins.trac.wordpress.org/changeset/3508033"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')","cweId":"CWE-89","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","baseScore":4.9,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"san6051"}],"timeline":[{"time":"2026-09-18T19:42:56.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-6295","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-19T13:23:44.016400Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-19T14:01:23.686Z"}}]}}
