{"cve":"CVE-2026-15404","nvd":{"published":"2026-07-23T10:16:50.560","modified":"2026-07-23T15:14:51.013","status":"Deferred","description":"The Lpagery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post titles in versions up to, and including, 2.5.7. This is due to insufficient input sanitization and output escaping in the lpagery_add_filter_text_template_post() function, which is hooked to admin_footer and echoes the raw post_title of the post referenced by the ?lpagery_template query parameter directly inside a JavaScript single-quoted string literal, without esc_js(), esc_html(), or any other encoding. 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 higher-privileged user (such as an administrator) accesses an admin page with the ?lpagery_template=<post_id> parameter pointing at the attacker's post.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/lpagery/tags/2.5.7/lpagery.php#L502","https://plugins.trac.wordpress.org/browser/lpagery/tags/2.5.7/lpagery.php#L504","https://plugins.trac.wordpress.org/browser/lpagery/tags/2.5.7/lpagery.php#L513","https://plugins.trac.wordpress.org/changeset?reponame=&old=3611156%40lpagery&new=3611156%40lpagery","https://www.wordfence.com/threat-intel/vulnerabilities/id/6720e68e-16fc-48c2-ad56-1f44a3e78bb2?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:53.305392138+00:00"},"epss":{"cve":"CVE-2026-15404","score":0.00331,"percentile":0.2636,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
