Technical Summary
CVE-2026-1509 is a code injection vulnerability (CWE-94) in the Avada (Fusion) Builder WordPress plugin. The issue arises from the output_action_hook() function accepting user-controlled input to invoke any registered WordPress action hook without proper authorization. Authenticated attackers with at least Subscriber privileges can exploit this to execute arbitrary WordPress actions, potentially leading to privilege escalation or other impacts depending on the hooks present in the WordPress environment. The vulnerability affects all versions up to and including 3.15.1. No patch or official remediation level has been published as of the data provided.
Potential Impact
An attacker with Subscriber-level access or higher can trigger arbitrary WordPress action hooks, which may result in privilege escalation, file inclusion, denial of service, or other security impacts depending on the hooks available in the WordPress installation. The CVSS score of 5.4 reflects a medium severity with network attack vector, low attack complexity, and no user interaction required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict user roles to trusted users only and consider disabling or limiting use of the Dynamic Data feature in the Avada (Fusion) Builder plugin if possible.
