CVE-2026-10553 weaverlancegmailcom CVE debrief

The jQuery Hover Footnotes plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) in all versions up to, and including, 1.4. This vulnerability is due to missing or incorrect nonce validation on the jqFootNotes_options_subpanel function. An unauthenticated attacker can exploit this vulnerability to update the plugin's settings with arbitrary values. Because option values such as jqfoot_anchor_open, jqfoot_anchor_close, and jqfoot_title are echoed unescaped into frontend page content, this can be chained into persistent Cross-Site Scripting (XSS) affecting all site visitors via a forged request, provided the attacker can trick a site administrator into performing an action such as clicking on a link.
