Summary
CVE-2026-16298 is a critical broken-authentication vulnerability in the FoodBoxBooker WordPress plugin. The plugin fails to properly validate password reset requests, allowing an unauthenticated attacker to reset the password of any user account — including administrators. Successful exploitation can lead to full takeover of the WordPress site and is rated Critical (CVSS 9.8).
Technical details
- Root cause: The plugin’s password reset workflow does not properly validate the reset request, so it fails to confirm that the requester is the legitimate owner of the account (CWE-269: Improper Privilege Management).
- Trigger conditions: No authentication or user interaction is required; an attacker only needs network access to the target WordPress site running the vulnerable plugin.
- Attack vector: Remote/network (AV:N) — the flaw is exploited by sending crafted password reset requests directly to the affected plugin’s endpoint.
- Impact: An attacker can reset the password of any user, including WordPress administrators, gaining full administrative access to the site. This can lead to complete compromise of confidentiality, integrity, and availability of the site and its data.
Affected software
- FoodBoxBooker WordPress plugin — all versions prior to 1.0.7
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Upgrade the FoodBoxBooker plugin to version 1.0.7 or later, which resolves the improper password reset validation.
- If immediate patching is not possible:
- Deactivate the FoodBoxBooker plugin until the update can be applied.
- Monitor for anomalous password reset activity or unexpected administrator account changes.
- Enforce multi-factor authentication for administrator accounts where supported, and review active administrator sessions/accounts for signs of compromise.
- Restrict or monitor access to WordPress admin and password-reset endpoints at the network/WAF layer as an interim compensating control.
