CVE-2025-68540: 
WordPress vulnerability analysis and mitigation

CVE-2025-68540 is a PHP Local File Inclusion (LFI) vulnerability in the thembay Fana WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects all versions of the Fana theme up to and including 1.1.35, with version 1.1.36 containing the fix. The vulnerability was reported by João Pedro S Alcântara (Kinorth) on November 28, 2025, and published by Patchstack on December 28, 2025. It carries a CVSS v3.1 base score of 7.5 (High) (Patchstack).

The root cause is improper input validation in the Fana theme's PHP file inclusion logic, where user-controlled input is passed to include/require statements without adequate sanitization or allowlisting (CWE-98). This allows an attacker with at least Contributor or Developer-level privileges to manipulate the filename parameter used in PHP file inclusion calls, causing the server to include arbitrary local files. The attack vector is network-based with high attack complexity and requires low privileges, meaning it is not exploitable by completely unauthenticated users. No public proof-of-concept code has been identified at this time (Patchstack).

Successful exploitation allows an attacker to read arbitrary local files on the web server, including sensitive configuration files such as wp-config.php (which contains database credentials), potentially enabling complete database takeover. Confidentiality, integrity, and availability are all rated as high impact, meaning a successful attack could expose credentials, allow unauthorized data modification, and disrupt service availability. In certain server configurations, LFI vulnerabilities can be chained with other techniques (e.g., log poisoning) to achieve remote code execution (Patchstack).

There is no known public proof-of-concept exploit and no evidence of active in-the-wild exploitation at this time. The EPSS score is approximately 0.0015 (0.15%), indicating a low probability of exploitation in the near term. Exploitation requires at least Contributor or Developer-level access to the WordPress site, which limits the attack surface compared to unauthenticated vulnerabilities. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog (Patchstack).

The primary remediation is to update the Fana WordPress theme to version 1.1.36 or later, which contains the fix for this vulnerability. As interim mitigations, administrators should implement strict input validation for any file inclusion mechanisms, use allowlists for permitted file paths, and apply the principle of least privilege to WordPress user roles. Conducting a security audit of the WordPress environment and monitoring for suspicious file access attempts is also recommended (Patchstack).

The vulnerability was covered in Wordfence's weekly WordPress vulnerability report for the period of December 15, 2025 to January 4, 2026, and received brief mentions on social media platforms including Mastodon (TheHackerWire) and Bluesky. Patchstack, the assigning CNA, rated the priority as "Low" and noted it is unlikely to be exploited in its current form. No significant broader industry commentary or vendor statements beyond the Patchstack advisory have been identified.
