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"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-03T18:39:48.465932Z","id":"CVE-2026-6453","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-03T18:39:59.351Z"}}]}}
