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. Exploitation requires the victim page to contain an Author Filter block alongside a grid or live-filter block, and execution is triggered by a visitor clicking the attacker's author entry in the dropdown — a standard filter interaction requiring no elevated privileges from the victim."}],"title":"Smart Post <= 4.0.9 - Authenticated (Subscriber+) Stored Cross-Site Scripting via User display_name via Author Filter block","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a5612c16-9629-4869-8ec1-8fba788b7d7c?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/post-carousel/tags/4.0.8/blocks/includes/class-template-part.php#L1146"},{"url":"https://plugins.trac.wordpress.org/browser/post-carousel/tags/4.0.8/blocks/assets/js/script.js#L1744"},{"url":"https://plugins.trac.wordpress.org/browser/post-carousel/tags/4.0.8/blocks/includes/class-template-part.php#L1130"},{"url":"https://plugins.trac.wordpress.org/changeset/3775298/post-carousel"},{"url":"https://plugins.trac.wordpress.org/changeset/3775298/post-carousel/trunk/blocks/assets/js/script.js"}],"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":"2026-10-29T15:06:10.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-30T20:12:18.000Z","lang":"en","value":"Disclosed"}]}}}
