CVE-2025-64634: 
WordPress vulnerability analysis and mitigation

CVE-2025-64634 is a Missing Authorization (Broken Access Control) vulnerability in the ThemeFusion Avada WordPress theme that allows unauthenticated or low-privileged attackers to access functionality not properly constrained by ACLs. It affects Avada versions up to and including 7.13.2, with version 7.13.3 being the patched release. The vulnerability was reported by João Pedro S Alcântara (Kinorth) on September 3, 2025, and published by Patchstack on December 16, 2025. It carries a CVSS v3.1 base score of 5.3 (Medium) (Patchstack).

The vulnerability is classified as CWE-862 (Missing Authorization), meaning certain privileged functionality within the Avada theme lacks proper authorization or nonce token checks, allowing requests from unauthenticated or subscriber-level users to reach restricted endpoints. The attack vector is network-based, requires no user interaction, and has low attack complexity, making it straightforward to exploit remotely. The specific functionality affected has not been publicly detailed beyond the broken access control classification, but the pattern is consistent with WordPress themes that expose AJAX actions or REST API endpoints without adequate capability checks (Patchstack).

Successful exploitation allows an attacker to access or invoke restricted theme functionality without proper authorization, resulting in a low integrity impact with no direct confidentiality or availability impact per the CVSS assessment. In practice, this could enable unauthorized modification of theme settings or content accessible through the unprotected functionality. The vulnerability is rated low priority by Patchstack, indicating limited real-world impact in most configurations, though it could serve as a stepping stone in a broader attack chain against WordPress installations (Patchstack).

There is no public proof-of-concept exploit code and no evidence of active in-the-wild exploitation at this time. The EPSS score is approximately 0.017%, reflecting a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies this as low priority, noting it is unlikely to be exploited despite the potential for use in mass-exploit campaigns targeting WordPress themes (Patchstack).

The primary remediation is to update the Avada theme to version 7.13.3 or later, which resolves the missing authorization issue. Site administrators unable to update immediately should review and restrict user permissions to the minimum required roles, and monitor for unauthorized access attempts. A security audit of the WordPress installation is also recommended to identify any signs of prior exploitation (Patchstack).
