CVE-2026-10553: CWE-352 Cross-Site Request Forgery (CSRF) in weaverlancegmailcom jQuery Hover Footnotes
The jQuery Hover Footnotes plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4. This is due to missing or incorrect nonce validation on the jqFootnotes_options_subpanel function. This makes it possible for unauthenticated attackers to update the plugin's settings with arbitrary values that, because option values such as jqfoot_anchor_open, jqfoot_anchor_close, and jqfoot_title are echoed unescaped into frontend page content, can be chained into persistent Cross-Site Scripting affecting all site visitors via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Successful exploitation of the CSRF vulnerability can be chained into stored Cross-Site Scripting, as the overwritten option values are persisted via update_option() without sanitization and rendered unescaped on the frontend.
AI Analysis
Technical Summary
CVE-2026-10553 is a CSRF vulnerability in the jQuery Hover Footnotes WordPress plugin (up to version 1.4) caused by missing or incorrect nonce validation on the jqFootnotes_options_subpanel function. This allows attackers to update plugin settings without authentication. Because certain option values (jqfoot_anchor_open, jqfoot_anchor_close, jqfoot_title) are stored without sanitization and output unescaped on the frontend, the CSRF can be chained into persistent stored XSS affecting site visitors. The vulnerability requires tricking an administrator into performing an action (e.g., clicking a link). There is no known patch or official fix at this time.
Potential Impact
An attacker can exploit the CSRF vulnerability to modify plugin settings with arbitrary values, which can lead to persistent stored Cross-Site Scripting (XSS) on the affected WordPress site. This impacts the integrity of the site by allowing injection of malicious scripts that execute in the browsers of site visitors. Confidentiality and availability impacts are not indicated. There are no known exploits in the wild currently.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should avoid clicking on untrusted links while logged into WordPress and consider disabling or removing the vulnerable plugin to prevent exploitation.
