On April 15 2026 the Avada (Fusion) Builder plugin for WordPress was identified as vulnerable to sensitive information exposure. This flaw affects any site running versions up to 3.15.1 and allows authenticated users with Subscriber-level access or higher to retrieve protected post metadata via the Dynamic Data feature.
What we know
The vulnerability is documented by CVE-2026-1541, published on April 15 2026 at 1:25 a.m. It arises from the fusion_get_post_custom_field() function failing to validate whether metadata keys are protected (underscore-prefixed). Attackers can extract data that should remain private, such as API keys or admin credentials.

Business Impact
SMB owners and enterprises using WordPress sites that rely on the Avada Fusion Builder will be exposed to the leakage of sensitive data. This can lead to:
- Revenue loss – compromised API keys could interrupt service integrations.
- Data exposure – private metadata might be shared with third parties or competitors.
- Regulatory risk – breach of GDPR, HIPAA, or other compliance requirements if sensitive information is disclosed.
For instance, a small online retailer using Avada for site design may unintentionally expose its payment gateway credentials, causing payment failures and customer trust erosion.
What to do
- Patch immediately – upgrade the plugin to version 3.16 or newer. Apply updates within 48 hours.
- Audit settings – review Dynamic Data usage; disable any features that expose protected metadata.
- Restrict access – limit Subscriber-level permissions for users who should not view private data.
- If upgrading is impossible – temporarily remove the Dynamic Data feature or set a stricter validation rule in your custom code.
These steps mitigate exposure and protect business integrity.
The bigger picture
WordPress plugins frequently suffer from insecure direct object references, especially when metadata keys are not properly validated. The trend underscores the need for vigilant plugin management and regular security audits.
