CVE-2026-1541Avada (Fusion) Builder <= 3.15.1 - Authenticated (Subscriber+) Sensitive Information Exposure via Insecure Direct Object Reference
Medium 4.3
In plain English
A medium-severity authorization bypass via user-controlled key in Avada (Fusion) Builder from themefusion. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 21% of all known vulnerabilities).
Official description
The Avada (Fusion) Builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.15.1. This is due to the plugin's `fusion_get_post_custom_field()` function failing to validate whether metadata keys are protected (underscore-prefixed). This makes it possible for authenticated attackers, with Subscriber-level access and above, to extract protected post metadata fields that should not be publicly accessible via the Dynamic Data feature's `post_custom_field` parameter.
