CVE-2026-75816 shabti CVE debrief

Who should care

WordPress site administrators, security teams responsible for WordPress deployments, and users of the Frontend Admin by DynamiApps plugin should assess exposure and take necessary actions to protect their sites and users.

Why it matters

CVE-2026-75816 is a critical vulnerability in the Frontend Admin by DynamiApps plugin for WordPress, allowing unauthenticated attackers to potentially take over user accounts. WordPress site administrators and security teams should assess exposure and apply patches or mitigations as soon as possible. The vulnerability's critical CVSS score of 9.8 indicates its severity. However, specific details on exploitation or victim impact are not provided in the CVE record or NVD entry, so verification of exposure and impact is necessary.

• Potential for unauthenticated attackers to take over user accounts, including administrator accounts.
• Ability for attackers to overwrite user email addresses, which can be used to reset passwords and gain control of accounts.
• Potential disruption to WordPress site operations and security if left unpatched.
• Need for verification of current plugin version and exposure in WordPress deployments.

Technical summary

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to, and including, 3.29.12. The vulnerability stems from the pre_update_value function lacking any capability or ownership check, and ActionPost::conditions_logic() short-circuiting its current_user_can('edit_post') authorization gate whenever the post ID is non-numeric. This allows unauthenticated form submissions to be routed to arbitrary user records without restriction, enabling attackers to overwrite any user's registered email address, including an administrator's, and then leverage WordPress's native password-reset flow to fully take over the targeted account.

Defensive priority

High priority for WordPress site administrators and security teams to assess exposure and apply patches or mitigations.

Recommended defensive actions

• Assess exposure of WordPress sites using the Frontend Admin by DynamiApps plugin, versions up to and including 3.29.12.
• Verify if the plugin has been updated to a patched version.
• Implement additional monitoring for suspicious account activity, especially related to email changes and password resets.
• Consider applying compensating controls, such as additional authentication steps for sensitive user account changes.
• Review and update asset inventory to ensure all instances of the plugin are accounted for.
• Establish a rollback plan in case patching is delayed or unsuccessful.
• Track changes to plugin versions and configurations for auditing and compliance purposes.
