CVE-2026-22408: 
WordPress vulnerability analysis and mitigation

CVE-2026-22408 is a Local File Inclusion (LFI) vulnerability in the Mikado-Themes Justicia WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects all versions of the Justicia theme through version 1.2 and was published on March 5, 2026. The vulnerability carries a CVSS v3.1 base score of 8.1 (High), reflecting high impacts to confidentiality, integrity, and availability with no privileges or user interaction required, though exploitation complexity is rated High (Feedly, Patchstack).

The root cause is improper control of filename parameters used in PHP include/require statements within the Justicia theme (CWE-98), which allows an attacker to manipulate file path inputs to include arbitrary local files from the server's filesystem. The attack vector is network-based and requires no authentication or user interaction, though the high attack complexity suggests that specific conditions or knowledge of the target environment may be needed to successfully exploit the flaw. The vulnerability is mapped to CAPEC-193 (PHP Remote File Inclusion), though the actual exploitation path is local file inclusion rather than remote (Feedly, Patchstack).

Successful exploitation allows a network-based attacker to include and execute arbitrary local files on the web server, potentially exposing sensitive configuration files (e.g., wp-config.php containing database credentials), executing malicious PHP code already present on the server, and achieving full compromise of the WordPress application and underlying server. The vulnerability poses high risks to confidentiality, integrity, and availability, and could facilitate lateral movement within the hosting environment or data theft (Feedly).

As of the time of reporting, there is no public proof-of-concept exploit code and no evidence of active in-the-wild exploitation. 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. The CVE was assigned by Patchstack and disclosed on March 5, 2026 (Feedly).

1. Reconnaissance: Identify WordPress sites using the Justicia theme (version ≤ 1.2) via passive fingerprinting tools such as WhatCMS, Wappalyzer, or by inspecting HTML source for theme-specific paths (e.g., /wp-content/themes/justicia/).
2. Identify vulnerable parameter: Analyze the theme's PHP source code or observed HTTP requests to locate parameters that are passed unsanitized to PHP include/require statements.
3. Craft malicious request: Construct an HTTP request that supplies a manipulated file path value to the vulnerable parameter, targeting sensitive local files such as ../../../../wp-config.php or log files that may contain injected PHP code.
4. Achieve file inclusion: Submit the crafted request to the target server; if successful, the server will include and potentially execute the specified local file, exposing its contents or executing embedded PHP code.
5. Escalate access: Use exposed credentials (e.g., from wp-config.php) or executed code to gain further access to the database, WordPress admin panel, or underlying server (Feedly).

• 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 file path manipulation patterns targeting the Justicia theme directory; HTTP 200 responses to requests containing traversal sequences.
• File System: Unexpected access to sensitive files such as wp-config.php, /etc/passwd, or PHP session files from the web server process; presence of PHP web shells in the theme or uploads directory.
• Process: Unusual child processes spawned by the web server (e.g., bash, curl, wget) that may indicate code execution following successful LFI exploitation (Feedly).

No patch has been confirmed available for the Justicia theme as of the disclosure date; users should check with Mikado-Themes for an updated version beyond 1.2. As interim mitigations, administrators should implement PHP's open_basedir directive to restrict file system access, apply web application firewall (WAF) rules to detect and block path traversal and file inclusion attempts, and enforce strict input validation on all theme parameters. Monitoring web server logs for traversal patterns and considering temporary deactivation of the theme until a patch is available are also recommended (Feedly, Patchstack).

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 coverage within the WordPress security community (Wordfence). It was also catalogued by VulDB shortly after disclosure. No significant broader media coverage or notable researcher commentary beyond routine vulnerability reporting has been identified.
