The parameter is read via $_POST['notinstring'] and passed through sanitize_text_field() \u2014 which strips HTML and whitespace but does not provide SQL safety. The value is then concatenated directly into a numeric/unquoted `AND id NOT IN (...)` clause and executed via $wpdb->get_results() without $wpdb->prepare() or intval() casting. Because the value sits in an unquoted numeric context, WordPress's wp_magic_quotes protection (which only escapes embedded quotes) is ineffective. The AJAX hook is registered via wp_ajax_nopriv_wprp_load_more_revs, and the required check_ajax_referer nonce is publicly available via wp_localize_script on any frontend page that renders the plugin shortcode, so an unauthenticated attacker who can reach a public page hosting the plugin can extract arbitrary data from the database via blind/time-based injection."}], "title": "WP Review Slider Pro <= 12.7.2 - Unauthenticated SQL Injection via 'notinstring' Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/396ba24f-e0f7-4374-a9ce-d9abddb87b39?source=cve"}, {"url": "https://wpreviewslider.userecho.com/knowledge-bases/2/articles/88-change-log"}], "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": "h0xilo"}], "timeline": [{"time": "2026-05-22T19:26:50.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-01T21:02:44.000Z", "lang": "en", "value": "Disclosed"}]}}}
