The handler is registered as 'wp_ajax_nopriv_filtersFrontend' and performs no capability or nonce check; raw POST data is JSON-decoded into $filterSettings and the attacker-controlled 'default_query' array is unconditionally array_merge()'d into the WP_Query arguments, overriding the plugin's safe defaults (most notably post_status, post_type, posts_per_page, and nopaging). This makes it possible for unauthenticated attackers to enumerate non-public WooCommerce products (draft, future, pending) — including their count and rendered listing markup — and to force unbounded queries that load all products in a single request.","epss":{"date":"2026-11-06","percentile":0.14049,"score":0.00231},"exploits":[],"kev":null,"metrics":[{"score":5.3,"severity":"medium","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},{"score":5.3,"severity":"medium","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"}],"modifiedAt":1793990206297,"publishedAt":1793429064344,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f2b51837-5925-497f-bdb8-c32f9011830b?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/woo-product-filter/trunk/modules/woofilters/controller.php#L864"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3757178%40woo-product-filter&new=3757178%40woo-product-filter"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/woo-product-filter/trunk/modules/woofilters/controller.php#L864"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3757178%40woo-product-filter&new=3757178%40woo-product-filter"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f2b51837-5925-497f-bdb8-c32f9011830b?source=cve"}],"remediation":[],"revision":"f3cf59a9003a5f2d4f9603bdf751b6be62b3a09c6e6de49cb16df6701d01eee4","sources":[{"modifiedAt":1793990206297,"name":"CNA: Wordfence","retrievedAt":1793992176408,"url":"https://www.cve.org/CVERecord?id=CVE-2026-11396"},{"modifiedAt":1793636359997,"name":"NVD","retrievedAt":1793643484910,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11396"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793992177714,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-11396"}],"ssvc":{"assessedAt":1793990195485,"automatable":"yes","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Product Filter for WooCommerce by WBW <= 3.4.6 - Missing Authorization to Unauthenticated Information Disclosure via filterSettings[default_query] Parameter","updatedAt":1793992177714}
