CVE-2025-68539: 
WordPress vulnerability analysis and mitigation

CVE-2025-68539 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). It affects all versions of the Fana theme up to and including 1.1.35, and was discovered by researcher João Pedro S Alcântara (Kinorth) on November 28, 2025, with public disclosure on February 11, 2026. The vulnerability carries a CVSS v3.1 base score of 8.1 (High) (Patchstack, Red Hat CVE).

The root cause is improper control of filename parameters passed to PHP include/require statements within the Fana WordPress theme (CWE-98), enabling an unauthenticated attacker to manipulate file path inputs and cause the server to include arbitrary local files. The attack vector is network-based with high attack complexity and requires no privileges or user interaction. Exploitation involves crafting HTTP requests that supply a malicious filename value to a vulnerable include/require code path, causing the server to read and potentially expose the contents of sensitive local files (Patchstack, Red Hat CVE).

Successful exploitation allows an unauthenticated remote attacker to include and render arbitrary local files from the server, potentially exposing sensitive credentials such as database configuration files (e.g., wp-config.php), which could lead to full database compromise. The vulnerability carries high confidentiality, integrity, and availability impacts — attackers may read sensitive data, modify application behavior by including malicious files already present on the server, or disrupt service. Depending on server configuration and the presence of attacker-controlled files (e.g., via file upload), LFI may escalate to remote code execution (Patchstack).

No public proof-of-concept exploit code or evidence of active in-the-wild exploitation has been observed as of the time of reporting. The EPSS score is approximately 0.053% (0.000530), indicating a low current probability of exploitation in the near term. No threat actor attribution or CISA KEV catalog listing has been identified for this CVE (Feedly, Patchstack).

1. Reconnaissance: Identify WordPress sites using the Fana theme (version ≤ 1.1.35) via passive scanning tools (e.g., WPScan, Shodan) or by inspecting theme metadata in publicly accessible style.css files.
2. Identify vulnerable parameter: Analyze the theme's PHP source code or observed HTTP responses to locate the endpoint and parameter that is passed unsanitized to a PHP include/require statement.
3. Craft malicious request: Construct an HTTP request (GET or POST) supplying a path traversal payload (e.g., ../../../../wp-config.php) as the filename parameter to the vulnerable endpoint.
4. Retrieve sensitive files: Submit the crafted request and observe the server response for the contents of the targeted local file, such as WordPress database credentials from wp-config.php.
5. Escalate if possible: If the server allows inclusion of attacker-controlled files (e.g., previously uploaded files with PHP content), attempt to escalate LFI to remote code execution by including a malicious file (Patchstack).

• Network: Unusual HTTP requests containing path traversal sequences (e.g., ../, ..%2F, ....//) in query parameters or POST body fields targeting the Fana theme endpoints.
• Logs: Web server access logs showing requests with encoded or plaintext directory traversal patterns to theme-related PHP scripts; HTTP 200 responses to requests with suspicious filename parameters.
• File System: Unexpected access to sensitive files such as wp-config.php, /etc/passwd, or other system files reflected in PHP error logs or access logs.
• Process: PHP error log entries indicating failed or successful file inclusion of paths outside the web root, or inclusion of uploaded files with PHP content.

The patched version of the Fana WordPress theme is 1.1.36, which resolves this vulnerability — all users should update immediately from the WordPress theme repository. As interim mitigations: disable allow_url_include in php.ini if not required; implement strict input validation and whitelisting for any filename parameters used in include/require statements; apply the principle of least privilege to web server file access permissions; and deploy a Web Application Firewall (WAF) rule to detect and block path traversal and file inclusion attempts. Patchstack has issued a virtual patch/mitigation rule for subscribers unable to update immediately (Patchstack).

Patchstack classified this vulnerability as high priority and noted it is the type of vulnerability commonly used in mass-exploit campaigns targeting WordPress sites regardless of traffic size or popularity. The vulnerability was responsibly disclosed by researcher João Pedro S Alcântara (Kinorth) and published by Patchstack on February 11, 2026. Wordfence also referenced the vulnerability in their weekly WordPress vulnerability report for the period of February 9–15, 2026 (Patchstack, Wordfence).
