{"cve":"CVE-2026-6453","nvd":{"published":"2026-08-01T09:17:02.530","modified":"2026-08-12T21:00:37.147","status":"Deferred","description":"The CubeWP Framework plugin for WordPress is vulnerable to SQL Injection in all versions up to and including 1.1.30. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-89"],"references":["https://plugins.trac.wordpress.org/browser/cubewp-framework/tags/1.1.29/cube/functions/admin-functions.php#L2655","https://plugins.trac.wordpress.org/browser/cubewp-framework/tags/1.1.29/cube/modules/custom-fields/class-cubewp-relationships.php#L251","https://plugins.trac.wordpress.org/browser/cubewp-framework/tags/1.1.29/cube/modules/custom-fields/class-cubewp-relationships.php#L261","https://plugins.trac.wordpress.org/browser/cubewp-framework/trunk/cube/functions/admin-functions.php#L2655","https://plugins.trac.wordpress.org/browser/cubewp-framework/trunk/cube/modules/custom-fields/class-cubewp-relationships.php#L251"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-6453","score":0.00472,"percentile":0.40872,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
