CVE-2025-69071: 
WordPress vulnerability analysis and mitigation

CVE-2025-69071 is a PHP Local File Inclusion (LFI) vulnerability in the AncoraThemes TanTum WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects TanTum versions from n/a through 1.1.13 and was disclosed on January 22, 2026, by Patchstack. The vulnerability carries a CVSS v3.1 base score of 8.1 (High), as assessed by CISA-ADP (NVD, Feedly).

The root cause is improper control of filename parameters used in PHP include/require statements within the TanTum theme (CWE-98). An attacker can manipulate file path inputs to cause the PHP interpreter to include arbitrary local files from the server's filesystem. Exploitation requires network access but no user interaction; however, attack complexity is rated High, suggesting specific conditions or configurations must be met. No public proof-of-concept or detailed technical write-up has been identified at this time (NVD, Feedly).

Successful exploitation can result in unauthorized disclosure of sensitive server-side files (e.g., configuration files containing database credentials), integrity compromise, and potential remote code execution if an attacker can chain the LFI with a file upload or log poisoning technique. The CVSS assessment reflects High impact across confidentiality, integrity, and availability, meaning a fully compromised WordPress host is a realistic outcome. Lateral movement within a shared hosting environment is also possible if sensitive credentials are exposed through included files (NVD, Feedly).

There is no public proof-of-concept exploit and no evidence of active in-the-wild exploitation as of the time of reporting. The EPSS score is approximately 0.053%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been identified (Feedly).

1. Reconnaissance: Identify WordPress sites using the TanTum theme (version ≤ 1.1.13) via passive techniques such as HTTP response headers, theme stylesheet references (/wp-content/themes/tantum/style.css), or tools like WPScan.
2. Identify vulnerable parameter: Locate the theme functionality that accepts a filename or path parameter for PHP file inclusion — typically exposed via a GET or POST parameter in a theme template or AJAX handler.
3. Craft LFI payload: Construct a request with a path traversal payload (e.g., ../../../../etc/passwd or ../../../../wp-config.php) in the vulnerable parameter to attempt inclusion of sensitive local files.
4. Retrieve sensitive data: If successful, the server response will contain the contents of the included file, potentially exposing database credentials, secret keys, or other sensitive configuration data from wp-config.php.
5. Escalate (optional): Chain the LFI with a previously uploaded file (e.g., a PHP web shell uploaded via a media upload feature) to achieve remote code execution on the server (NVD, Feedly).

• Network: HTTP requests to WordPress endpoints associated with the TanTum theme containing path traversal sequences (e.g., ../, ..%2F, %2e%2e%2f) in query parameters or POST body fields.
• Logs: WordPress or web server access logs showing requests to theme-related PHP files with unusual file, path, template, or include parameters containing traversal strings; HTTP 200 responses to such requests may indicate successful inclusion.
• File System: Unexpected PHP files or web shells appearing in the WordPress uploads directory (/wp-content/uploads/) or theme directory.
• Process: Unusual child processes spawned by the web server process (e.g., apache2, nginx, php-fpm) such as bash, curl, or wget, which may indicate post-exploitation activity following LFI-to-RCE escalation.

The primary remediation is to update the TanTum theme to a version greater than 1.1.13 as soon as a patched release is available from AncoraThemes. No specific patched version has been confirmed in available data. As interim mitigations: restrict access to the WordPress admin and theme functionality to trusted users only; implement a Web Application Firewall (WAF) rule to block path traversal patterns in HTTP requests; disable PHP execution in upload directories; and monitor server logs for suspicious file inclusion attempts. If the theme is not actively needed, consider deactivating or removing it until a patch is released (NVD, Feedly).

The vulnerability was reported by Patchstack, which assigned and disclosed the CVE on January 22, 2026.
