This is due to insufficient input sanitization on the wrapper attribute. The plugin uses esc_html() to escape the value, but esc_html() only encodes HTML entities and does not prevent attribute injection when the value is used as an HTML tag name in a sprintf() call. An attacker can inject event handler attributes via spaces in the wrapper value. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Since it is also possible for administrators to make this functionality available to lower-privileged users, this introduces the possibility of abuse by contributors.","severity":{"version":"3.1","score":5.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00274,"percentile":0.19948,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2026-05-05T02:26:56Z","modified":"2026-10-28T02:30:22Z","products":[{"vendor":"publishpress","product":"schedule post changes with publishpress future: unpublish, delete, change status, trash, change categories"}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9acf80aa-8354-4430-9836-18fa17854521?source=cve","tags":["web"]},{"url":"https://plugins.trac.wordpress.org/browser/post-expirator/trunk/src/Modules/Expirator/Controllers/ShortcodeController.php#L173","tags":["web"]},{"url":"https://plugins.trac.wordpress.org/browser/post-expirator/tags/4.9.4/src/Modules/Expirator/Controllers/ShortcodeController.php#L173","tags":["web"]},{"url":"https://github.com/publishpress/publishpress-future/releases","tags":["package"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-5247","tags":["advisory"]},{"url":"https://github.com/advisories/GHSA-p9xc-cphq-3q9h"},{"url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/5xxx/CVE-2026-5247.json","tags":["advisory"]}],"sources":{"cve":[{"id":"CVE-2026-5247","title":"Schedule Post Changes With PublishPress Future: Unpublish, Delete, Change Status, Trash, Change Categories \u003c= 4.10.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'wrapper' Shortcode Attribute","description":"The Schedule Post Changes With PublishPress Future plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wrapper' attribute of the [futureaction] shortcode in all versions up to, and including, 4.10.0.
