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."}], "title": "WP-Members Membership Plugin <= 3.5.7 - Authenticated (Subscriber+) Stored Cross-Site Scripting via WooCommerce Checkout Multicheckbox/Multiselect Field", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/3872211b-b7d9-4d71-a371-9099392b4678?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/admin/class-wp-members-admin-users.php#L555"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/api/api-forms.php#L540"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/api/api-forms.php#L372"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/vendor/rocketgeek-utilities/includes/forms.php#L143"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.7/includes/api/api-forms.php#L530"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&new=3753517%40wp-members%2Ftrunk&old=3686809%40wp-members%2Ftrunk"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-members/tags/3.5.8/includes/admin/class-wp-members-admin-users.php"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-79 Improper Neutralization of Input During Web Page Generation", "cweId": "CWE-79", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N", "baseScore": 6.4, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "Jacek Sowi\u0144ski (dzaku)"}], "timeline": [{"time": "2026-09-23T13:43:34.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-11-06T22:49:51.000Z", "lang": "en", "value": "Disclosed"}]}, "adp": [{"metrics": [{"other": {"type": "ssvc", "content": {"id": "CVE-2026-96565", "role": "CISA Coordinator", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "version": "2.0.3", "timestamp": "2026-11-07T17:59:59.921587Z"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-11-07T18:06:01.374Z"}}]}}
