CVE-2026-22457: 
WordPress vulnerability analysis and mitigation

CVE-2026-22457 is a Local File Inclusion (LFI) vulnerability in the Mikado-Themes Wanderland WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects all versions of the Wanderland theme through version 1.5. The vulnerability was published on March 5, 2026, with the CVE assigned by Patchstack. It carries a CVSS v3.1 base score of 8.1 (High), exploitable remotely without authentication, though with high attack complexity (Feedly, EUVD).

The root cause is improper control of filename parameters used in PHP include/require statements within the Wanderland theme (CWE-98), which allows an attacker to manipulate file path inputs to include arbitrary local files on the server. Despite being classified under the 'PHP Remote File Inclusion' CWE, the actual exploitation vector is Local File Inclusion (LFI), meaning attackers can include files already present on the server's filesystem rather than remote URLs. Exploitation requires no authentication and no user interaction, though the high attack complexity rating suggests that specific conditions or knowledge of the server's file structure may be needed. No public proof-of-concept code has been identified at this time (Feedly, Patchstack).

Successful exploitation allows unauthenticated attackers to include and execute arbitrary local files on the server, potentially exposing sensitive configuration files (e.g., wp-config.php containing database credentials), executing PHP code present on the filesystem, and achieving full compromise of the WordPress installation. This can result in high confidentiality, integrity, and availability impacts, including unauthorized data disclosure, content modification, and potential lateral movement within the hosting environment if credentials or other sensitive data are extracted (Feedly).

There is currently no evidence of public proof-of-concept exploit code or active in-the-wild exploitation of CVE-2026-22457. The EPSS score is approximately 0.053%, indicating a low probability of exploitation in the near term. No threat actor attribution has been made, and the vulnerability does not appear in the CISA Known Exploited Vulnerabilities (KEV) catalog at this time (Feedly).

1. Reconnaissance: Identify WordPress sites using the Wanderland theme (version ≤ 1.5) via passive techniques such as inspecting page source for theme references (e.g., /wp-content/themes/wanderland/) or using tools like WPScan.
2. Identify vulnerable parameter: Locate the theme's PHP file(s) that accept user-controlled filename input passed to an include or require statement — typically via GET/POST parameters or URL path segments.
3. Craft LFI payload: Construct a request with a manipulated filename parameter designed to traverse directories and include a sensitive local file, e.g., ?file=../../../../wp-config.php or similar path traversal sequences.
4. Extract sensitive data: If successful, the server returns the contents of the included file (e.g., database credentials from wp-config.php, system files like /etc/passwd).
5. Escalate: Use extracted credentials or session tokens to gain administrative access to the WordPress dashboard or the underlying database, enabling further compromise or lateral movement (Feedly).

• Network: HTTP requests to WordPress theme files containing path traversal sequences (e.g., ../, %2e%2e%2f) in query parameters; unusual GET/POST requests targeting Wanderland theme PHP files with file path parameters.
• Logs: Web server access logs showing requests to /wp-content/themes/wanderland/ endpoints with suspicious parameter values containing directory traversal patterns; HTTP 200 responses to requests with encoded traversal sequences.
• File System: Unexpected access to sensitive files such as wp-config.php, /etc/passwd, or other system files by the web server process; new or modified files in the theme directory.
• Process: PHP processes reading files outside the expected web root or theme directory (Feedly).

No official patch has been released for the Wanderland theme as of the time of publication. The recommended immediate action is to disable or remove the Wanderland theme (version 1.5 and earlier) from all affected WordPress installations until a patched version is available. As a compensating control, implement Web Application Firewall (WAF) rules to detect and block path traversal and file inclusion attempts targeting the theme. Additionally, review server access logs for signs of exploitation and ensure WordPress file permissions are properly restricted to limit the impact of any LFI attempt (Feedly, Patchstack).

The vulnerability was reported and assigned by Patchstack, a WordPress security firm that specializes in identifying and disclosing WordPress plugin and theme vulnerabilities. No notable researcher commentary, vendor statements beyond the initial disclosure, or significant media coverage has been identified for this CVE at this time (Feedly).
