EXECUTIVE SUMMARY:
Critical vulnerabilities discovered in the Avada Builder plugin for WordPress pose a significant security risk, potentially allowing unauthorized access to sensitive server-side information and the execution of arbitrary database queries. Impacting approximately one million installations, these flaws involve an arbitrary file read vulnerability and a time-based SQL injection with scores reaching a high-severity rating of 7.5. Exploitation of these weaknesses could lead to the full compromise of database credentials and cryptographic keys. Immediate remediation is essential to maintain the integrity and confidentiality of affected web environments. CVE-2026-4782: This arbitrary file read vulnerability exists within the fusion_get_svg_from_file function when processing custom shortcode parameters. With a CVSS score of 6.5, it is classified as Medium severity because it requires an attacker to have authenticated subscriber-level access. The lack of file type or source validation allows these users to retrieve sensitive local files like wp-config.php. Successful exploitation provides attackers with database credentials and critical system salts, facilitating deeper environment penetration. The presence of these vulnerabilities highlights a critical need for rigorous input validation and the adoption of secure coding practices. Administrators must ensure that all components are updated to the latest secure versions to mitigate the risk of data theft and unauthorized system access. Failure to address these issues leaves the underlying infrastructure exposed to persistent exploitation attempts.[/subscribe_to_unlock_form]
