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 Sowiński (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"}}]}}
