Impact and Attack Scenarios
The core impact of CVE-2026-1541 lies in the potential exposure of sensitive post metadata. This metadata could contain confidential information such as internal notes, pricing details, or other data not intended for public consumption. An attacker with Subscriber access could leverage the fusiongetpostcustomfield() function and the Dynamic Data feature to retrieve this information by manipulating the postcustomfield parameter. While requiring authentication, the relatively low access threshold (Subscriber) significantly broadens the potential attack surface. The blast radius extends to any WordPress site utilizing the vulnerable Avada Builder plugin and storing sensitive data within post metadata.
Exploitation Context
CVE-2026-1541 was published on April 14, 2026. Its severity is rated as Medium. Currently, there are no publicly available exploits or active campaigns targeting this vulnerability. The vulnerability is not listed on KEV or EPSS, suggesting a low probability of immediate exploitation.

Mitigation and Workarounds
The primary mitigation for CVE-2026-1541 is to immediately upgrade the Avada (Fusion) Builder plugin to version 3.15.2 or later. If upgrading is not immediately feasible due to compatibility issues or breaking changes, consider temporarily restricting access to the Dynamic Data feature or implementing stricter access controls for users with Subscriber roles. While not a direct fix, a Web Application Firewall (WAF) could be configured to block requests attempting to access protected metadata fields via the postcustomfield parameter. Regularly review and audit post metadata fields to ensure sensitive information is not inadvertently exposed.
How to fix
Update to version 3.15.2, or a newer patched version
