CVE-2026-22415: 
WordPress vulnerability analysis and mitigation

CVE-2026-22415 is a PHP Local File Inclusion (LFI) vulnerability in the AncoraThemes "The Mounty" WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects all versions of The Mounty theme through version 1.1. The vulnerability was published on March 5, 2026, and was assigned by Patchstack. It carries a CVSS v3.1 base score of 8.1 (High), exploitable remotely without authentication or user interaction, though with high attack complexity (Feedly, Patchstack).

The root cause is improper control of filename parameters used in PHP include/require statements within the theme (CWE-98), which allows an attacker to manipulate file path inputs to include arbitrary local files from the server's filesystem. This class of vulnerability arises when user-supplied input is passed unsanitized to PHP file inclusion functions, enabling traversal to sensitive files outside the intended directory. The attack vector is network-based, requires no privileges or user interaction, but does require high attack complexity, suggesting some precondition such as specific server configuration or parameter guessing may be necessary (Feedly).

Successful exploitation of this LFI vulnerability could allow an unauthenticated remote attacker to read sensitive files from the server (e.g., configuration files containing credentials, /etc/passwd), potentially modify application functionality or data, and disrupt service availability. In worst-case scenarios, if combined with file upload capabilities or log poisoning techniques, LFI can escalate to Remote Code Execution (RCE), leading to full server compromise. All three pillars of security — confidentiality, integrity, and availability — are rated as HIGH impact (Feedly).

As of the time of reporting, there is no public proof-of-concept exploit and no evidence of active in-the-wild exploitation. The EPSS score is approximately 0.053%, indicating a low probability of exploitation in the near term. The vulnerability has not been added to the CISA Known Exploited Vulnerabilities (KEV) catalog. The high attack complexity rating further reduces the immediate risk of widespread opportunistic exploitation (Feedly).

1. Reconnaissance: Identify WordPress sites using the "The Mounty" theme (version ≤ 1.1) via passive fingerprinting tools such as WPScan, Shodan, or by inspecting theme-related HTTP response headers and HTML source.
2. Identify vulnerable parameter: Analyze the theme's PHP source code or observed HTTP requests to locate parameters passed to PHP include/require functions without proper sanitization.
3. Craft LFI payload: Construct a malicious HTTP request with a manipulated filename parameter using directory traversal sequences (e.g., ../../../../etc/passwd) targeting the vulnerable endpoint.
4. Exfiltrate sensitive files: Submit the crafted request to the target server and retrieve the contents of sensitive files such as WordPress wp-config.php (containing database credentials) or system files.
5. Escalate if possible: Attempt log poisoning or leverage uploaded files to escalate the LFI to Remote Code Execution if server conditions permit (Feedly).

• Network: Unusual HTTP GET or POST requests to theme-related endpoints containing directory traversal sequences (e.g., ../, ..%2F, ....//) in file path parameters.
• Logs: WordPress or web server access logs showing repeated requests with encoded path traversal patterns targeting The Mounty theme files; HTTP 200 responses to requests referencing system files like /etc/passwd or wp-config.php.
• File System: Unexpected access to sensitive files outside the WordPress web root; new or modified files in the theme directory that were not part of the original installation.
• Process: Unusual PHP process activity reading files outside the WordPress installation directory.

Users should update The Mounty theme to a version newer than 1.1 as soon as a patched release becomes available from AncoraThemes. In the interim, the following mitigations are recommended:

• Deploy Web Application Firewall (WAF) rules to detect and block file inclusion payloads containing directory traversal sequences.
• Restrict PHP file system permissions to limit the files accessible by the web server process.
• Disable unnecessary PHP functions (e.g., allow_url_include) in php.ini to reduce the attack surface.
• Monitor web server and WordPress access logs for suspicious file inclusion attempts targeting the theme (Feedly).

The vulnerability was noted in the Wordfence Intelligence Weekly WordPress Vulnerability Report covering the period of February 23 to March 1, 2026, indicating it received standard industry tracking attention. No significant independent researcher commentary or broader media coverage has been identified beyond routine vulnerability database entries (Wordfence Blog).
