{"cve":"CVE-2026-10738","nvd":{"published":"2026-06-09T05:16:29.963","modified":"2026-07-23T08:10:00.137","status":"Deferred","description":"The jQuery Hover Footnotes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Footnote Qualifier ('{{...}}' Syntax) in all versions up to, and including, 1.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The attribute-breakout payload (e.g., a double-quote followed by an event handler) contains no angle brackets and therefore bypasses WordPress core's wp_kses_post() filtering, which only strips disallowed HTML tags rather than sanitizing attribute contexts.","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/jquery-hover-footnotes/trunk/jqFootnotes.php#L213","https://plugins.trac.wordpress.org/browser/jquery-hover-footnotes/trunk/jqFootnotes.php#L222","https://plugins.trac.wordpress.org/browser/jquery-hover-footnotes/trunk/jqFootnotes.php#L235","https://plugins.trac.wordpress.org/browser/jquery-hover-footnotes/trunk/jqFootnotes.php#L246","https://www.wordfence.com/threat-intel/vulnerabilities/id/b02bdf2a-1d99-4cc3-8f75-822ff0792e44?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-10738","score":0.00253,"percentile":0.16889,"date":"2026-10-31"},"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).
