This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is only exploitable via the WooCommerce classic checkout path, as the sibling registration, profile, and account-edit handlers implode the value before sanitization, which raises a PHP 8 TypeError on scalar input and fails closed.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.4,"severity":"medium","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794050787608,"publishedAt":1794050787608,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3872211b-b7d9-4d71-a371-9099392b4678?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/admin/class-wp-members-admin-users.php#L555"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/api/api-forms.php#L540"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/api/api-forms.php#L372"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/vendor/rocketgeek-utilities/includes/forms.php#L143"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/api/api-forms.php#L530"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3753517%40wp-members%2Ftrunk&old=3686809%40wp-members%2Ftrunk"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.8/includes/admin/class-wp-members-admin-users.php"}],"remediation":[],"revision":"7d8b89fd41db26b4920b13fb63dd4796ba4cad06696ea2c458857e26829f2dfd","sources":[{"modifiedAt":1794050787608,"name":"CNA: Wordfence","retrievedAt":1794053423655,"url":"https://www.cve.org/CVERecord?id=CVE-2026-96565"}],"ssvc":null,"status":"published","title":"WP-Members Membership Plugin <= 3.5.7 - Authenticated (Subscriber+) Stored Cross-Site Scripting via WooCommerce Checkout Multicheckbox/Multiselect Field","updatedAt":1794053423655}
