CVE-2026-1086 Overview
The Font Pairing Preview For Landing Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) in all versions up to, and including, 1.3. This vulnerability stems from missing nonce validation on the settings update functionality. The flaw enables unauthenticated attackers to modify the plugin's font pairing settings via a forged request, provided they can trick a site administrator into performing an action such as clicking on a malicious link.
Critical Impact
Unauthenticated attackers can manipulate plugin settings through social engineering, potentially altering site appearance or injecting malicious content through modified font configurations.
Affected Products
- Font Pairing Preview For Landing Pages plugin for WordPress versions up to and including 1.3

Technical Details for CVE-2026-1086
Vulnerability Analysis
This Cross-Site Request Forgery vulnerability exists in the Font Pairing Preview For Landing Pages WordPress plugin due to inadequate security controls in the settings management functionality. The plugin fails to implement proper nonce verification when processing requests to update font pairing configurations. Nonces (Number used Once) are security tokens used in WordPress to verify that requests originate from legitimate users and are not forged by malicious actors.
Without nonce validation, the plugin cannot distinguish between authentic administrator-initiated requests and forged requests crafted by attackers. This allows attackers to construct malicious web pages or links that, when visited by an authenticated administrator, will execute unintended actions on the WordPress site.
Root Cause
The root cause of CVE-2026-1086 is the absence of WordPress nonce verification in the settings update handler within wp-font-pairing-settings.php. The vulnerable code processes settings updates without calling wp_verify_nonce() or check_admin_referer(), which are the standard WordPress functions for validating request authenticity. This omission bypasses WordPress's built-in CSRF protection mechanism.
Attack Vector
The attack vector for this vulnerability is network-based and requires user interaction. An attacker would craft a malicious HTML page containing a hidden form or JavaScript that submits a forged request to the WordPress admin endpoint responsible for updating font pairing settings. The attacker then needs to deceive a logged-in site administrator into visiting this malicious page, either through phishing emails, compromised websites, or social engineering tactics.
When the administrator visits the malicious page while authenticated to their WordPress site, the forged request executes with the administrator's privileges, modifying the plugin's font settings without their knowledge or consent.
Detection Methods for CVE-2026-1086
Indicators of Compromise
- Unexpected changes to font pairing settings in the WordPress admin panel
