CVE-2025-69396: 
WordPress vulnerability analysis and mitigation

CVE-2025-69396 is a PHP Local File Inclusion (LFI) vulnerability in the ThemeREX Splendour WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects all versions of the Splendour theme through version 1.23 and allows unauthenticated remote attackers to include and execute arbitrary local files on the server. The vulnerability was published on February 20, 2026, and carries a CVSS v3.1 base score of 8.1 (High) (Feedly).

The root cause is improper validation and sanitization of filename parameters used in PHP include/require statements within the Splendour theme (CWE-98). An attacker can manipulate these parameters to point to arbitrary local files on the server filesystem, causing PHP to include and potentially execute them. 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 configurations must be met. The vulnerability is mapped to CAPEC-193 (PHP Remote File Inclusion), though the actual impact is local file inclusion (Feedly, Wordfence).

Successful exploitation allows an attacker to read and potentially execute arbitrary local files on the web server, including sensitive configuration files, database credentials, WordPress wp-config.php, and other server-side source code. This can lead to full compromise of the web application and the underlying server, unauthorized data exfiltration, and potential lateral movement if credentials obtained from configuration files are reused elsewhere. Confidentiality, integrity, and availability are all rated as High impact (Feedly).

As of the available data, there is no public proof-of-concept exploit and no confirmed in-the-wild exploitation of CVE-2025-69396. The EPSS score is approximately 0.053%, indicating a low current probability of exploitation in the near term. The vulnerability has not been added to the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported (Feedly).

1. Reconnaissance: Identify WordPress sites using the ThemeREX Splendour theme version 1.23 or earlier using 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 use fuzzing tools to locate the specific include/require statement that accepts user-controlled filename input without proper sanitization.
3. Craft malicious request: Construct an HTTP request targeting the vulnerable parameter with a path traversal payload (e.g., ../../../../wp-config.php) to reference a sensitive local file.
4. Exfiltrate sensitive data: If the included file is returned in the HTTP response or causes a detectable error, extract credentials, API keys, or other sensitive information from files such as wp-config.php.
5. Escalate access: Use obtained database credentials or other secrets to gain deeper access to the WordPress database, admin panel, or underlying server infrastructure (Feedly).

• Network: Unusual HTTP requests containing path traversal sequences (e.g., ../, ..%2F, ....//) in query parameters or POST body fields targeting the Splendour theme endpoints.
• Logs: WordPress or web server access logs showing repeated requests with encoded path traversal strings to theme-related PHP files; 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 by the web server process.
• Process: Web server processes (e.g., Apache, Nginx, PHP-FPM) spawning unexpected child processes or making outbound network connections following suspicious file inclusion requests (Feedly).

No official patch has been confirmed as available for the ThemeREX Splendour theme at the time of disclosure. Site administrators should immediately audit all installations running Splendour version 1.23 or earlier and consider temporarily disabling or replacing the theme until a fix is released. As interim mitigations: restrict web server access to theme directories, implement a Web Application Firewall (WAF) rule to block path traversal patterns, disable PHP allow_url_include in php.ini, and monitor server logs for suspicious file inclusion attempts. Contact ThemeREX directly for patch availability and upgrade timelines (Feedly).

The vulnerability was noted in Wordfence's weekly WordPress vulnerability report for the period of February 9–15, 2026, indicating it was tracked by the WordPress security community shortly after disclosure. No significant vendor statements, researcher commentary, or broader media coverage has been identified beyond standard vulnerability database listings (Wordfence).
