This is due to insufficient input sanitization in the cubewp_remove_relation() AJAX function, specifically the use of wp_unslash() on the relation_id parameter before interpolating it directly into a raw SQL query without using $wpdb->prepare(). The wp_unslash() call explicitly removes the backslash escaping that WordPress's wp_magic_quotes() adds to all $_POST data, neutralizing the only layer of SQL injection protection. The sanitize_text_field() function applied afterward offers no SQL protection. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries to the existing query."}], "title": "CubeWP Framework <= 1.1.30 - Authenticated (Subscriber+) SQL Injection via 'relation_id' Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/a4647620-e06a-49d5-8f9d-a59cb5a999b1?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/cubewp-framework/trunk/cube/functions/admin-functions.php#L2655"}, {"url": "https://plugins.trac.wordpress.org/browser/cubewp-framework/trunk/cube/modules/custom-fields/class-cubewp-relationships.php#L261"}, {"url": "https://plugins.trac.wordpress.org/browser/cubewp-framework/tags/1.1.29/cube/modules/custom-fields/class-cubewp-relationships.php#L261"}, {"url": "https://plugins.trac.wordpress.org/browser/cubewp-framework/trunk/cube/modules/custom-fields/class-cubewp-relationships.php#L251"}, {"url": "https://plugins.trac.wordpress.org/browser/cubewp-framework/tags/1.1.29/cube/modules/custom-fields/class-cubewp-relationships.php#L251"}, {"url": "https://plugins.trac.wordpress.org/browser/cubewp-framework/tags/1.1.29/cube/functions/admin-functions.php#L2655"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&old=3627740%40cubewp-framework&new=3627740%40cubewp-framework"}], "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:L/UI:N/S:U/C:H/I:N/A:N", "baseScore": 6.5, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "Louis Deschanel (JeanJeanLeHaxor)"}, {"lang": "en", "type": "finder", "value": "Pascal SUN"}], "timeline": [{"time": "2026-04-16T20:09:12.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-31T20:01:04.000Z", "lang": "en", "value": "Disclosed"}]}}}
