{"cve":"CVE-2026-3138","nvd":{"published":"2026-03-24T05:16:23.727","modified":"2026-06-17T10:43:06.420","status":"Deferred","description":"The Product Filter for WooCommerce by WBW plugin for WordPress is vulnerable to unauthorized data loss due to a missing capability check in all versions up to, and including, 3.1.2. This is due to the plugin's MVC framework dynamically registering unauthenticated AJAX handlers via `wp_ajax_nopriv_` hooks without verifying user capabilities, combined with the base controller's `__call()` magic method forwarding undefined method calls to the model layer, and the `havePermissions()` method defaulting to `true` when no permissions are explicitly defined. This makes it possible for unauthenticated attackers to truncate the plugin's `wp_wpf_filters` database table via a crafted AJAX request with `action=delete`, permanently destroying all filter configurations.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","score":6.5},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/woo-product-filter/tags/3.1.0/classes/controller.php#L99","https://plugins.trac.wordpress.org/browser/woo-product-filter/tags/3.1.0/classes/frame.php#L280","https://plugins.trac.wordpress.org/browser/woo-product-filter/tags/3.1.0/classes/frame.php#L416","https://plugins.trac.wordpress.org/browser/woo-product-filter/tags/3.1.0/classes/table.php#L345","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3487143%40woo-product-filter%2Ftrunk&old=3479545%40woo-product-filter%2Ftrunk&sfp_email=&sfph_mail=#file2"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-3138","score":0.00284,"percentile":0.20951,"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).
