{"id":"CVE-2026-10738","state":"PUBLISHED","title":"jQuery Hover Footnotes <= 1.4 - Authenticated (Author+) Stored Cross-Site Scripting via Footnote Qualifier ('{{...}}' Syntax)","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.","publishedAt":"2026-06-09T03:41:22.446Z","updatedAt":"2026-06-09T15:13:13.489Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["weaverlancegmailcom jQuery Hover Footnotes"],"affected":[{"vendor":"weaverlancegmailcom","product":"jQuery Hover Footnotes","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b02bdf2a-1d99-4cc3-8f75-822ff0792e44?source=cve","https://plugins.trac.wordpress.org/browser/jquery-hover-footnotes/trunk/jqFootnotes.php#L246","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#L213","https://plugins.trac.wordpress.org/browser/jquery-hover-footnotes/trunk/jqFootnotes.php#L222"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:10:33.477Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/10xxx/CVE-2026-10738.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-10738","state":"PUBLISHED","datePublished":"2026-06-09T03:41:22.446Z","dateUpdated":"2026-06-09T15:13:13.489Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-03T13:04:14.546Z"},"containers":{"cna":{"title":"jQuery Hover Footnotes <= 1.4 - Authenticated (Author+) Stored Cross-Site Scripting via Footnote Qualifier ('{{...}}' Syntax)","descriptions":[{"lang":"en","value":"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.
