CVE-2025-68536: 
WordPress vulnerability analysis and mitigation

CVE-2025-68536 is a PHP Local File Inclusion (LFI) vulnerability in the thembay Zota WordPress theme, affecting versions up to and including 1.3.14. The flaw is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program) and allows unauthenticated remote attackers to include and execute arbitrary local files on the server. It was reported by researcher João Pedro S Alcântara (Kinorth) on November 27, 2025, and published by Patchstack 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 validation and sanitization of user-controlled input used in PHP include/require statements within the Zota WordPress theme (CWE-98). An attacker can manipulate a filename parameter passed to these PHP file inclusion functions to reference arbitrary local files on the server's filesystem, bypassing intended access controls. Exploitation requires no authentication and no user interaction, though attack complexity is rated High, suggesting some precondition such as knowledge of file paths or specific server configuration. No public proof-of-concept code has been identified at this time (Patchstack, Red Hat CVE).

Successful exploitation allows an unauthenticated attacker to read and potentially execute arbitrary local files on the web server, including sensitive configuration files such as wp-config.php which contains database credentials. This can lead to full database compromise, exposure of secret keys, and depending on server configuration, remote code execution if attacker-controlled content can be included. The vulnerability has high impact on confidentiality, integrity, and availability of the affected WordPress installation (Patchstack).

No public proof-of-concept exploit or active in-the-wild exploitation has been observed as of the time of reporting. The EPSS score is approximately 0.053%, indicating a low current probability of exploitation. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack notes that vulnerabilities of this class (LFI with CVSS 8.1) are frequently used in mass-exploit campaigns targeting WordPress sites regardless of traffic or popularity (Patchstack, Red Hat CVE).

1. Reconnaissance: Identify WordPress sites using the Zota theme version 1.3.14 or earlier via tools like 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 requests to locate the file inclusion point where user-controlled input is passed to a PHP include/require statement without proper sanitization.
3. Craft malicious request: Send an unauthenticated HTTP request to the vulnerable endpoint with a manipulated filename parameter pointing to a sensitive local file (e.g., ../../../../wp-config.php or /etc/passwd) using path traversal sequences.
4. Extract sensitive data: Review the server's HTTP response for the contents of the included file, which may expose database credentials, secret keys, or other sensitive configuration data.
5. Escalate if possible: If the server configuration permits (e.g., PHP wrappers are enabled or attacker-controlled files exist on the server), attempt to include a file containing PHP code to achieve remote code execution (Patchstack).

• Network: Unusual HTTP GET or POST requests to WordPress theme endpoints containing path traversal sequences (e.g., ../, ..%2F, %2e%2e%2f) in query parameters or POST body fields.
• Logs: Web server access logs showing requests with encoded path traversal patterns targeting theme-related PHP files; HTTP 200 responses to requests containing file path parameters pointing to system files like /etc/passwd or wp-config.php.
• File System: Unexpected access timestamps on sensitive files such as wp-config.php, /etc/passwd, or other configuration files that should not be directly served by the web application.
• Process: PHP processes reading files outside the WordPress web root directory, observable via system audit logs (e.g., auditd on Linux) (Patchstack).

The patched version of the Zota WordPress theme is 1.3.15, which resolves this vulnerability. Site administrators should update the Zota theme to version 1.3.15 or later immediately. If an immediate update is not possible, consider restricting access to the WordPress site at the network level, or use a Web Application Firewall (WAF) such as Patchstack, which has issued a virtual patch/mitigation rule to block exploitation attempts until the theme is updated. Additionally, monitor application logs for path traversal patterns as a detection measure (Patchstack).

Patchstack flagged this vulnerability as high priority, noting that LFI vulnerabilities with this CVSS score are commonly leveraged in mass-exploit campaigns against WordPress sites. The Wordfence Intelligence weekly WordPress vulnerability report for February 9–15, 2026 also referenced this CVE. No significant broader media coverage or notable researcher commentary beyond these security vendor reports has been identified (Wordfence, Patchstack).
