CVE-2025-31005: Easyfonts Plugin CSRF Vulnerability

CVE-2025-31005 Overview

CVE-2025-31005 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Uzair Easyfonts plugin for WordPress. The flaw exists in all plugin versions up to and including 1.1.2. The vulnerability is classified under CWE-352 and requires user interaction to exploit. An attacker can craft a malicious request that, when triggered by an authenticated user visiting an attacker-controlled page, performs unintended state-changing actions in the plugin. The vulnerability affects integrity but does not directly expose confidential data or cause service disruption.

Critical Impact
Attackers can trick authenticated WordPress administrators into performing unintended plugin configuration changes through forged HTTP requests.

Affected Products

Uzair Easyfonts WordPress plugin versions up to and including 1.1.2
WordPress installations with the Easyfonts plugin enabled
Any site using vulnerable Easyfonts versions with authenticated administrator sessions

Technical Details for CVE-2025-31005

Vulnerability Analysis

The Easyfonts plugin fails to implement proper CSRF protections on state-changing endpoints. WordPress plugins typically use nonces generated by wp_create_nonce() and validated via check_admin_referer() or wp_verify_nonce(). When these validation checks are missing or improperly implemented, attackers can forge requests on behalf of authenticated users. The EPSS score is 0.22% with a percentile of 12.44, indicating a low predicted exploitation probability. However, the vulnerability remains exploitable when an authenticated administrator interacts with attacker-controlled content.

Root Cause

The root cause is the absence of anti-CSRF token verification on sensitive plugin actions. Requests submitted to the vulnerable endpoints are processed based solely on the user's authenticated session cookie. The plugin does not verify that the request originated from a legitimate form within the WordPress admin interface. This allows cross-origin submissions to succeed when accompanied by valid session credentials.

Attack Vector

Exploitation requires the attacker to lure an authenticated administrator to a malicious webpage or link. The attacker's page contains hidden HTML form submissions or JavaScript that issue requests to the target WordPress site. Because the browser automatically attaches the administrator's session cookies, the vulnerable endpoint processes the forged request. The attacker cannot read the response but can trigger configuration changes within the plugin.

No public proof-of-concept code is available for this vulnerability. Additional technical details are documented in the Patchstack EasyFonts Plugin Vulnerability advisory.

Detection Methods for CVE-2025-31005

Indicators of Compromise

Unexpected changes to Easyfonts plugin configuration or font settings without administrator action
HTTP POST requests to Easyfonts plugin endpoints with Referer headers pointing to external domains
WordPress admin actions logged from unusual client contexts or lacking corresponding admin panel navigation

Detection Strategies

Monitor web server access logs for requests to Easyfonts plugin URLs with foreign or missing Referer headers
Enable WordPress audit logging plugins to record plugin configuration changes and correlate against administrator activity
Review browser network telemetry for cross-origin form submissions targeting /wp-admin/ endpoints associated with Easyfonts

Monitoring Recommendations

Track administrator session activity and correlate configuration changes with active admin interface use
Deploy Web Application Firewall (WAF) rules that inspect Referer and Origin headers on state-changing WordPress requests
Alert on outbound HTTP requests from WordPress hosts to unrecognized domains that may indicate injected external resources

How to Mitigate CVE-2025-31005

Immediate Actions Required

Update the Easyfonts plugin to a version above 1.1.2 once a patched release is available from the vendor
Disable or remove the Easyfonts plugin if a patched version has not been published and the plugin is non-essential
Require administrators to log out of the WordPress dashboard when not actively performing administrative tasks

Patch Information

As of the last NVD update on 2026-06-17, the advisory identifies all versions through 1.1.2 as affected. Review the Patchstack advisory for the latest patched version guidance and remediation status.

Workarounds

Restrict WordPress admin access using IP allowlists at the web server or WAF layer
Enforce SameSite=Strict or SameSite=Lax cookie attributes on WordPress session cookies to block cross-origin request submission
Deploy WAF rules that reject POST requests to /wp-admin/ endpoints without valid Referer or Origin headers matching the site domain
Train administrators to avoid clicking untrusted links while logged into the WordPress dashboard

bash

# Example nginx configuration to enforce Referer validation on wp-admin
location ~ ^/wp-admin/ {
    if ($http_referer !~* ^https?://your-domain\.com) {
        return 403;
    }
}
