CVE-2026-22456: 
WordPress vulnerability analysis and mitigation

CVE-2026-22456 is a Local File Inclusion (LFI) vulnerability in the Elated-Themes Askka WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects all versions of the Askka theme up to and including version 1.0, with no official patch currently available. The vulnerability was reported by Tran Nguyen Bao Khanh (VCI - VNPT Cyber Immunity) on December 4, 2025, and publicly disclosed on March 3–5, 2026. It carries a CVSS v3.1 base score of 8.1 (High) (Patchstack, Feedly).

The root cause is improper control of filename parameters used in PHP include/require statements within the Askka theme (CWE-98), which maps to CAPEC-193 (PHP Remote File Inclusion). Despite the CWE classification referencing remote file inclusion, the exploitable attack vector in this case is Local File Inclusion (LFI), where an attacker can manipulate a filename parameter passed to a PHP include function to reference arbitrary files on the server's filesystem. Exploitation requires no authentication and no user interaction, though the attack complexity is rated High, suggesting specific conditions or non-default configurations must be met. No public proof-of-concept code has been identified at this time (Patchstack, Feedly).

Successful exploitation allows an unauthenticated remote attacker to include and render arbitrary local files from the server, potentially exposing sensitive data such as WordPress configuration files (e.g., wp-config.php) containing database credentials, application source code, and other protected server-side files. This could lead to full database compromise, credential theft, and further lateral movement within the hosting environment. Confidentiality, integrity, and availability are all rated as High impact (Patchstack, Feedly).

There is no evidence of active in-the-wild exploitation or a publicly available proof-of-concept at this time. 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 has noted that vulnerabilities of this class (CVSS 8.1 LFI) are frequently used in mass-exploit campaigns targeting WordPress sites at scale, and has issued a virtual patch/mitigation rule for its subscribers (Patchstack, Feedly).

1. Reconnaissance: Identify WordPress sites using the Askka theme (version ≤ 1.0) via passive scanning tools (e.g., 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 parameter that is insufficiently sanitized before being passed to a PHP include/require statement.
3. Craft LFI payload: Construct an HTTP request targeting the vulnerable endpoint with a manipulated filename parameter, such as path traversal sequences (e.g., ../../../../wp-config.php) to reference sensitive server files.
4. Extract sensitive data: Submit the crafted request and observe the server response for the contents of included files, such as database credentials from wp-config.php or other configuration data.
5. Escalate access: Use extracted credentials or application secrets to gain further access to the database, admin panel, or hosting environment for lateral movement or full site compromise (Patchstack).

• Network: Unusual HTTP GET or POST requests to Askka theme endpoints containing path traversal sequences (e.g., ../, ..%2F, %2e%2e%2f) in filename or path parameters.
• Logs: WordPress or web server access logs showing requests with encoded traversal patterns targeting theme PHP files; repeated 200 responses to requests with suspicious file path parameters.
• File System: Unexpected access to sensitive files such as wp-config.php, /etc/passwd, or server configuration files as reflected in PHP error logs or access logs.
• Process: PHP processes reading files outside the WordPress web root, which may appear in system audit logs (e.g., auditd on Linux) if file access auditing is enabled.

No official patch from Elated-Themes is currently available for the Askka theme. Patchstack has issued a virtual mitigation rule for its subscribers to block exploitation attempts until an official fix is released. Site owners should consider removing or replacing the Askka theme if a patch is not forthcoming, implementing Web Application Firewall (WAF) rules to detect and block LFI patterns, restricting PHP file system permissions to limit access to sensitive files, and monitoring application logs for suspicious file inclusion activity. Contacting the hosting provider for additional hardening options is also recommended (Patchstack, Feedly).

Wordfence included CVE-2026-22456 in its weekly WordPress vulnerability report for the period of March 2–8, 2026, highlighting it among notable theme vulnerabilities. Qualys added detection for this vulnerability (detection ID 531092) as part of its April 2026 application security detections release. Community attention has been limited, consistent with the absence of a public PoC or active exploitation (Wordfence, Qualys).
