CVE-2025-62117: 
WordPress vulnerability analysis and mitigation

CVE-2025-62117 is a Cross-Site Request Forgery (CSRF) vulnerability in the EasyIndex WordPress plugin developed by Jayce53. It affects all versions of EasyIndex through 1.1.1704 and allows unauthenticated attackers to perform unauthorized actions by tricking authenticated users into visiting a malicious page. The vulnerability was published on December 31, 2025, and assigned by Patchstack. It carries a CVSS v3.1 base score of 5.4 (Medium) (Feedly, EUVD).

The vulnerability is classified under CWE-352 (Cross-Site Request Forgery), meaning the plugin fails to properly validate or verify the origin of state-changing HTTP requests. An attacker can craft a malicious web page or link that, when visited by an authenticated WordPress administrator or user, silently submits forged requests to the EasyIndex plugin's endpoints. Because the plugin does not implement nonce verification or equivalent anti-CSRF protections, the server processes these requests as legitimate. No authentication is required on the attacker's side; only user interaction (visiting the malicious page) is needed (Feedly).

Successful exploitation can result in unauthorized modification of plugin data and potential disruption of availability, as reflected in the CVSS impact metrics (integrity: Low, availability: Low, confidentiality: None). An attacker who tricks an authenticated WordPress user into visiting a crafted page could alter EasyIndex plugin settings or data without the victim's knowledge. While the scope is limited to the affected plugin's functionality and does not directly expose sensitive data, repeated or targeted abuse could degrade site functionality (Feedly).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-62117. The EPSS score is approximately 0.015% (0.000150), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires social engineering to lure an authenticated WordPress user to a malicious page, which raises the practical bar for abuse (Feedly).

1. Reconnaissance: Identify WordPress sites running the EasyIndex plugin (version ≤ 1.1.1704) using tools like WPScan or by inspecting publicly accessible plugin directories.
2. Craft malicious request: Identify the EasyIndex plugin's state-changing endpoints (e.g., admin-post.php actions or plugin-specific AJAX handlers) that lack nonce verification.
3. Build CSRF payload: Create an HTML page containing a hidden form or JavaScript that automatically submits a forged POST/GET request to the target WordPress site's EasyIndex endpoint with attacker-controlled parameters.
4. Social engineering: Deliver the malicious page link to an authenticated WordPress administrator or editor via phishing email, comment, or other channel.
5. Trigger exploitation: When the victim visits the malicious page while logged into WordPress, their browser automatically sends the forged request with their session credentials, causing the plugin to execute the unauthorized action (Feedly).

• Logs: WordPress access logs showing unexpected POST requests to EasyIndex plugin endpoints (e.g., admin-post.php or admin-ajax.php with EasyIndex-specific action parameters) from unusual referrer URLs or external domains.
• Logs: WordPress audit logs (if enabled via plugins like WP Activity Log) recording unexpected changes to EasyIndex plugin settings without corresponding administrator activity.
• Network: HTTP requests to WordPress admin endpoints originating from non-admin IP addresses or with suspicious Referer headers pointing to external sites.

As of the disclosure date (December 31, 2025), no patched version of the EasyIndex plugin beyond 1.1.1704 has been confirmed as available. Site administrators should consider deactivating and removing the EasyIndex plugin until a patched version is released. As a general WordPress hardening measure, restrict access to the WordPress admin area by IP allowlisting and ensure all users follow the principle of least privilege. Monitor the plugin's repository and Patchstack advisories for patch availability (Feedly).

The vulnerability was reported and assigned by Patchstack, a WordPress security firm that operates a vulnerability disclosure program. No notable independent researcher commentary, vendor statements beyond the Patchstack advisory, or significant media coverage has been identified for this CVE, consistent with its medium severity and limited scope (Feedly).
