CVE-2025-62117 Overview
CVE-2025-62117 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Jayce53 EasyIndex WordPress plugin. The flaw impacts all versions of EasyIndex up to and including 1.1.1704. The vulnerability is categorized under [CWE-352] and stems from missing or improper CSRF token validation on state-changing requests.
An attacker can craft a malicious web page that, when visited by an authenticated EasyIndex user, triggers unauthorized actions in the plugin. Exploitation requires user interaction, but no privileges are needed on the attacker side.
Critical Impact
Attackers can forge authenticated requests to modify plugin state, resulting in limited integrity and availability impact on affected WordPress sites.
Affected Products
- Jayce53 EasyIndex plugin for WordPress
- All versions from initial release through 1.1.1704
- WordPress installations with EasyIndex enabled

Technical Details for CVE-2025-62117
Vulnerability Analysis
The vulnerability exists in the EasyIndex plugin request handling logic. State-changing endpoints do not properly validate anti-CSRF tokens or verify request origin. As a result, an attacker-controlled page can submit forged requests to the plugin using an authenticated victim's browser session.
Cross-Site Request Forgery abuses the trust a web application places in a user's browser. When a logged-in EasyIndex user visits a malicious page, the browser automatically attaches session cookies to any requests targeting the WordPress site. Without a valid CSRF nonce check on the receiving endpoint, the plugin processes the forged request as if it came from the legitimate user.
Root Cause
The root cause is missing or insufficient verification of WordPress nonces on plugin actions that modify state. Standard WordPress security practice requires wp_verify_nonce() or check_admin_referer() calls on sensitive handlers, along with capability checks. When these validations are absent or incorrectly implemented, endpoints become vulnerable to CSRF attacks per [CWE-352].
Attack Vector
Exploitation follows a standard CSRF pattern. An attacker hosts a malicious HTML page containing a hidden form or auto-submitting JavaScript that targets an EasyIndex endpoint. The attacker lures an authenticated administrator or user with plugin access to visit the page through phishing, forum posts, or malvertising. Upon page load, the victim's browser submits the request with valid session cookies attached, and the plugin executes the action.
The attack requires the victim to be authenticated to the target WordPress site at the time of visiting the malicious page. Refer to the Patchstack CSRF Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-62117
Indicators of Compromise
- Unexpected changes to EasyIndex plugin configuration or content not initiated by administrators
- HTTP referer headers pointing to external, untrusted domains on plugin action requests
- POST requests to EasyIndex endpoints originating from cross-origin contexts
- Anomalous administrative actions occurring shortly after users visit external links
Detection Strategies
- Review WordPress access logs for plugin endpoint requests with mismatched or missing Referer and Origin headers
- Monitor plugin audit logs for state changes correlated with user browsing sessions to external sites
- Implement web application firewall (WAF) rules that inspect referer and origin headers on plugin routes
- Deploy content security monitoring to identify unauthorized configuration drift in EasyIndex settings
Monitoring Recommendations
- Enable WordPress activity logging plugins to capture all administrative actions with source IP and referer
- Correlate authentication events with subsequent plugin modification events to identify suspicious patterns
- Alert on high-volume or rapid-fire plugin state changes that deviate from baseline administrator behavior
How to Mitigate CVE-2025-62117
Immediate Actions Required
- Disable the EasyIndex plugin until a patched version is confirmed available from the vendor
- Restrict administrative access to trusted networks using IP allowlisting on the WordPress admin interface
- Educate users with plugin access to avoid clicking untrusted links while authenticated to the WordPress site
- Review recent plugin activity logs to identify any unauthorized changes potentially caused by CSRF exploitation
Patch Information
At the time of publication, no fixed version beyond 1.1.1704 has been referenced in the available advisory data. Monitor the Patchstack CSRF Vulnerability Report and the WordPress plugin repository for vendor updates. Apply any released patch immediately upon availability.
Workarounds
- Deactivate and remove the EasyIndex plugin until a security update is released
- Deploy a WAF rule set that enforces same-origin policy on plugin endpoints by validating Origin and Referer headers
- Require re-authentication for sensitive WordPress administrative actions using short session timeouts
- Use browser session isolation, dedicating a separate browser profile for WordPress administration to reduce cross-site attack exposure
