CVE-2025-14976: 
WordPress vulnerability analysis and mitigation

CVE-2025-14976 is a Cross-Site Request Forgery (CSRF) vulnerability in the "User Registration & Membership – Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin" for WordPress, developed by WPEverest. It affects all versions up to and including 4.4.8, and allows unauthenticated attackers to delete arbitrary posts by tricking a site administrator into clicking a malicious link. The vulnerability was reported by Wordfence and published on January 10, 2026. It carries a CVSS v3.1 base score of 5.4 (Medium) (Wordfence, Red Hat CVE).

The root cause is missing or incorrect nonce validation (CWE-352) in the process_row_actions function when handling the delete action within the plugin's list table abstraction class (abstract-ur-list-table.php, line 290). Because no valid nonce is required to authenticate the request, an attacker can craft a forged HTTP request that, when executed in the context of an authenticated administrator's browser session, triggers the deletion of arbitrary WordPress posts. Exploitation requires social engineering — the attacker must trick a logged-in administrator into clicking a crafted link or visiting a malicious page that submits the forged request (Wordfence, WordPress Trac).

Successful exploitation allows an unauthenticated attacker to delete arbitrary posts on the affected WordPress site, resulting in low integrity and low availability impact with no confidentiality breach. This could lead to loss of site content, disruption of membership-gated resources, or corruption of user registration data managed by the plugin. While the impact is limited in scope (no remote code execution or credential theft), repeated exploitation could significantly degrade site functionality (Wordfence).

No public exploit code or active in-the-wild exploitation has been reported for CVE-2025-14976. The EPSS score is approximately 0.012% (0.000120), 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 user interaction (an administrator clicking a malicious link), which limits the attack surface compared to fully unauthenticated vulnerabilities (Wordfence, Red Hat CVE).

1. Reconnaissance: Identify WordPress sites running the "User Registration & Membership" plugin by WPEverest at version 4.4.8 or earlier, using tools like WPScan or by inspecting publicly visible plugin metadata.
2. Craft forged request: Construct a malicious URL or HTML page containing a hidden form or <img> tag that sends a GET or POST request to the target site's admin endpoint invoking process_row_actions with the delete action and a target post ID (e.g., https://target.com/wp-admin/admin.php?page=user-registration&action=delete&id=<POST_ID>).
3. Social engineering: Deliver the malicious link to a site administrator via email, chat, or a compromised third-party site, enticing them to click it while authenticated to the WordPress admin panel.
4. Trigger deletion: When the administrator clicks the link, their browser automatically sends the forged request with their session cookies, and the server processes the deletion without nonce verification, removing the targeted post (Wordfence, WordPress Trac).

• Logs: WordPress access logs showing unexpected GET/POST requests to /wp-admin/ pages associated with the User Registration plugin (page=user-registration) with action=delete parameters, originating from unusual referrers or external domains.
• Application: Unexplained disappearance of posts or pages on the WordPress site, particularly membership-restricted content or registration-related posts.
• Logs: WordPress audit logs (if enabled via a plugin such as WP Activity Log) recording post deletions attributed to an administrator account at unusual times or from unexpected IP addresses.

Users should update the "User Registration & Membership" plugin to version 4.4.9 or later, which includes the fix for missing nonce validation as reflected in the plugin changeset (WordPress Trac). No configuration-based workaround is available; the only effective remediation is applying the vendor patch. As a general precaution, administrators should avoid clicking unsolicited links while logged into the WordPress admin panel and consider using a web application firewall (WAF) with CSRF protection rules.

The vulnerability was reported and disclosed by Wordfence, which assigned the CVE and published the advisory. Coverage has been limited to automated vulnerability aggregators and security databases such as VulDB, Vulners, and CIRCL, with no notable researcher commentary or significant media coverage identified.
