This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. A Contributor can break out of the shortcode attribute context by embedding a ] character in the passster_id or passster_headline meta value to prematurely close the opening shortcode tag, then append a [/passster] closing tag so that the trailing HTML payload is emitted verbatim by do_shortcode() — bypassing the per-attribute escaping present inside render_shortcode() — and the script will also execute in an editor's or administrator's browser when they preview the Contributor's pending post, since filter_the_content() has no edit-permission capability gate."}],"id":"CVE-2026-125409","lastModified":"2026-11-13T10:17:28.443","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":6.4,"baseSeverity":"MEDIUM","confidentialityImpact":"LOW","integrityImpact":"LOW","privilegesRequired":"LOW","scope":"CHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"exploitabilityScore":3.1,"impactScore":2.7,"source":"security@wordfence.com","type":"Primary"}]},"published":"2026-11-13T10:17:28.317","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/content-protector/tags/4.3.21/inc/admin/inc/class-ps-meta.php#L82"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/content-protector/tags/4.3.21/inc/class-ps-public.php#L294"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/content-protector/tags/4.3.21/inc/class-ps-public.php#L417"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/content-protector/tags/4.3.21/inc/class-ps-public.php#L429"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/changeset/3793918/content-protector/trunk/inc/class-ps-public.php"},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/81cf06d2-9b5a-4f9f-adf9-890b46db7783?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-79"}],"source":"security@wordfence.com","type":"Primary"}]}
