CVE-2026-16298 Overview
CVE-2026-16298 is a critical authentication bypass vulnerability in the FoodBoxBooker WordPress plugin before version 1.0.7. The plugin fails to properly validate password reset requests, allowing unauthenticated attackers to reset the password of arbitrary users, including administrators. Successful exploitation leads to full site takeover through account compromise of privileged users.
The flaw is classified under [CWE-269] Improper Privilege Management. It requires no authentication, no user interaction, and can be exploited remotely over the network against any vulnerable WordPress site running the affected plugin.
Critical Impact
Unauthenticated attackers can hijack administrator accounts and gain complete control over affected WordPress sites, enabling content manipulation, malware injection, and data exfiltration.
Affected Products
- FoodBoxBooker WordPress plugin versions prior to 1.0.7
- WordPress installations with the vulnerable plugin activated
- Any site exposing the plugin's password reset functionality to unauthenticated users

Technical Details for CVE-2026-16298
Vulnerability Analysis
The FoodBoxBooker plugin exposes a password reset workflow that does not enforce proper validation on the reset request. An attacker can submit a crafted request that references an arbitrary username or user ID and receive or set a new password for that account. Because the flaw permits targeting any user, including the site administrator, the impact escalates from account takeover to complete site compromise.
The issue falls under Improper Privilege Management [CWE-269]. WordPress plugins that implement custom password reset flows must validate the requester's identity through cryptographically secure tokens tied to the target account. This plugin's implementation omits or improperly checks that binding, breaking the trust relationship between the reset token and the target user.
Once an attacker resets an administrator password, they can authenticate to /wp-admin, install malicious plugins or themes, create additional administrator accounts, pivot to the underlying host through PHP code execution primitives, and exfiltrate customer data stored in the WordPress database.
Root Cause
The root cause is missing or insufficient authorization checks in the plugin's password reset handler. The endpoint accepts a target user identifier without verifying that the requester owns or controls that account. No nonce validation, ownership check, or secure token binding prevents an attacker from directing the reset at an arbitrary user.
Attack Vector
Exploitation occurs over the network by sending a crafted HTTP request to the plugin's password reset endpoint. The attacker specifies the target account, such as the administrator's username or email, and completes the reset flow to obtain a new password. No prior authentication or user interaction is required. Refer to the WPScan Vulnerability Report for further technical detail.
Detection Methods for CVE-2026-16298
Indicators of Compromise
- Unexpected password reset events for administrator or privileged accounts in WordPress audit logs.
- New administrator accounts created shortly after a password reset event.
- Unusual plugin or theme installations following an administrator login from an unfamiliar IP address.
- HTTP requests to FoodBoxBooker password reset endpoints originating from unauthenticated sources.
Detection Strategies
- Inventory all WordPress sites for the FoodBoxBooker plugin and confirm versions against 1.0.7 or later.
- Review web server access logs for POST requests to the plugin's password reset endpoint referencing high-privilege usernames.
- Correlate password change events with subsequent administrator logins from new IP addresses or user agents.
Monitoring Recommendations
- Enable WordPress activity logging to capture user role changes, password resets, and plugin installations.
- Forward WordPress and web server logs to a centralized SIEM for correlation and alerting on privileged account changes.
- Alert on any password reset event targeting accounts with the administrator role.
How to Mitigate CVE-2026-16298
Immediate Actions Required
- Update the FoodBoxBooker plugin to version 1.0.7 or later on all WordPress installations.
- Force a password reset for all administrator and privileged accounts on sites that ran vulnerable plugin versions.
- Audit user accounts for unauthorized administrator additions and remove any that are not legitimate.
- Review recent plugin, theme, and file changes for signs of post-exploitation activity.
Patch Information
The vendor addressed the flaw in FoodBoxBooker version 1.0.7. The fix implements proper validation of password reset requests to prevent unauthenticated attackers from targeting arbitrary users. See the WPScan Vulnerability Report for advisory details.
Workarounds
- Deactivate the FoodBoxBooker plugin until the patched version is deployed.
- Restrict access to the plugin's password reset endpoint at the web application firewall (WAF) or reverse proxy layer.
- Enforce multi-factor authentication (MFA) on all WordPress administrator accounts to reduce takeover impact.
