This is due to insufficient escaping of user-supplied column names in the ajaxCheck() method and lack of preparation in the $wpdb->update() call. The vulnerability is compounded by the complete absence of authorization checks and the endpoint being registered for unauthenticated users via wp_ajax_nopriv_. This makes it possible for unauthenticated attackers to inject arbitrary SQL queries and extract sensitive information from the database via time-based blind SQL injection techniques, including administrator password hashes."}], "title": "WP CTA <= 2.2.2 - Unauthenticated Time-Based Blind SQL Injection via 'fildname' Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/7e963601-dc41-4218-9119-708c74e51bc2?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/easy-sticky-sidebar/tags/1.7.4/inc/ClassActions.php#L193"}, {"url": "https://plugins.trac.wordpress.org/browser/easy-sticky-sidebar/tags/1.7.4/inc/ClassActions.php#L186"}, {"url": "https://plugins.trac.wordpress.org/browser/easy-sticky-sidebar/tags/1.7.4/inc/ClassActions.php#L17"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&old=3524743%40easy-sticky-sidebar&new=3524743%40easy-sticky-sidebar"}], "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:N/UI:N/S:U/C:H/I:N/A:N", "baseScore": 7.5, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "daroo"}], "timeline": [{"time": "2026-07-10T16:57:59.000Z", "lang": "en", "value": "Disclosed"}]}}}
