CVE-2025-14996: 
WordPress vulnerability analysis and mitigation

CVE-2025-14996 is a privilege escalation via account takeover vulnerability in the AS Password Field In Default Registration Form plugin for WordPress. The flaw affects all versions up to and including 2.0.0 and allows unauthenticated attackers to change the password of any WordPress user, including administrators, thereby gaining full account access. It was published on January 6, 2026, and assigned by Wordfence. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical) (Wordfence, NVD).

The root cause is classified as CWE-639: Authorization Bypass Through User-Controlled Key — the plugin fails to properly validate a user's identity before processing a password update request, allowing an attacker to supply an arbitrary user identifier (e.g., user ID or username) as a key to target any account (Wordfence). The attack vector is network-based, requires no authentication, no user interaction, and low attack complexity, making it trivially exploitable remotely. The vulnerable code path can be reviewed in the plugin source at version 2.0.0 (Plugin Source). No public proof-of-concept exploit code has been identified at this time (Wordfence).

Successful exploitation grants an unauthenticated attacker the ability to reset the password of any WordPress user account, including site administrators, resulting in complete account takeover and full site compromise. An attacker with administrator-level access can install malicious plugins or themes, exfiltrate sensitive data, deface the site, create persistent backdoor accounts, and pivot to other systems or services connected to the WordPress environment. All three security pillars — confidentiality, integrity, and availability — are rated as high impact (Wordfence, NVD).

As of the time of reporting, no public proof-of-concept exploit code has been published and there is no confirmed evidence of in-the-wild exploitation (Wordfence). The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The EPSS score is approximately 0.074%, indicating a currently low probability of exploitation in the near term (Feedly). However, the zero-authentication requirement and critical CVSS score make it a high-priority target if exploitation tooling is developed.

1. Reconnaissance: Identify WordPress sites running the AS Password Field In Default Registration Form plugin (version ≤ 2.0.0) by scanning for the plugin's presence via common WordPress plugin enumeration techniques (e.g., checking /wp-content/plugins/as-password-field-in-default-registration-form/).
2. Identify target user: Enumerate WordPress usernames or user IDs via the WordPress REST API (/wp-json/wp/v2/users) or login error messages to identify administrator accounts.
3. Craft malicious request: Send an unauthenticated HTTP request to the plugin's password update endpoint, supplying the target user's identifier (e.g., user ID or login) as a user-controlled key parameter without any authentication token or nonce validation.
4. Set new password: Include a chosen new password in the request payload. Due to the missing identity validation, the plugin processes the update and changes the target user's password.
5. Account takeover: Log in to the WordPress admin panel (/wp-admin) using the target account's username and the newly set password, achieving full administrative access (Wordfence, Plugin Source).

• Network: Unexpected unauthenticated POST requests to WordPress endpoints associated with the AS Password Field plugin's password update functionality; unusual login activity from unfamiliar IP addresses following password change events.
• Logs: WordPress authentication logs (wp-login.php) showing successful admin logins from new or foreign IP addresses; server access logs with POST requests to plugin-specific endpoints without a valid session cookie or nonce.
• WordPress Activity: Unexpected administrator password change events in WordPress user management logs or audit plugins (e.g., WP Activity Log); new administrator accounts created shortly after a password change event.
• File System: Newly installed plugins or themes not authorized by site administrators; presence of web shells or backdoor files in the WordPress uploads or plugins directories.
• Process: Unusual outbound connections from the web server process following a successful login, potentially indicating post-exploitation activity such as data exfiltration or C2 communication.

No patched version of the AS Password Field In Default Registration Form plugin has been confirmed as available; the vulnerability affects all versions up to and including 2.0.0 (Wordfence). Immediate recommended actions:

• Deactivate and remove the plugin from all WordPress installations immediately.
• Audit administrator accounts for unauthorized password changes or suspicious login activity.
• Enforce strong, unique passwords and enable multi-factor authentication (MFA) on all WordPress admin accounts.
• Deploy a Web Application Firewall (WAF) such as Wordfence to detect and block unauthorized password reset attempts.
• Monitor for plugin developer updates and apply any security patch as soon as one becomes available.

Wordfence, the CNA that assigned and disclosed this CVE, published the vulnerability details in their threat intelligence portal on January 6, 2026 (Wordfence). The vulnerability was highlighted in Wordfence's weekly WordPress vulnerability report for the week of January 5–11, 2026 (Wordfence Blog). It was also referenced in the CISA vulnerability bulletin for the week of January 5, 2026, and received coverage from security aggregators including TheHackerWire and Infinit Security (CISA Bulletin, Infinit Security).
