CVE-2026-22425: Sweet Jane PHP File Inclusion Vulnerability

CVE-2026-22425 Overview

CVE-2026-22425 is a Local File Inclusion (LFI) vulnerability affecting the Sweet Jane WordPress theme developed by Elated-Themes. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files on the server. This can lead to sensitive information disclosure, configuration file exposure, and potentially remote code execution when combined with other attack techniques.

Critical Impact

Attackers can leverage this LFI vulnerability to read sensitive files from the WordPress installation, including configuration files containing database credentials, and potentially achieve code execution through log poisoning or other file inclusion chaining techniques.

Affected Products

• Elated-Themes Sweet Jane WordPress Theme version 1.2 and earlier
• WordPress installations using the Sweet Jane theme (sweetjane)

Technical Details for CVE-2026-22425

Vulnerability Analysis

This vulnerability is classified as CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Sweet Jane WordPress theme fails to properly validate and sanitize user-supplied input before using it in PHP include() or require() statements. This allows an attacker to manipulate file path parameters to traverse directories and include arbitrary files from the local file system.

Local File Inclusion vulnerabilities in WordPress themes are particularly dangerous because they can expose the wp-config.php file, which contains database credentials, authentication keys, and other sensitive configuration data. Additionally, attackers may chain this vulnerability with other techniques such as log poisoning to achieve remote code execution.

Root Cause

The root cause of this vulnerability lies in insufficient input validation within the Sweet Jane theme's PHP code. When the theme processes user-controlled input for file inclusion operations, it fails to implement proper sanitization measures such as:

• Blocking directory traversal sequences (../)
• Validating that included files reside within an expected directory
• Using allowlists for permitted file paths
• Properly escaping or filtering special characters in file paths

This oversight allows malicious actors to craft requests that manipulate the file path, ultimately including unintended files from the server's file system.

Attack Vector

The attack vector for CVE-2026-22425 involves sending specially crafted HTTP requests to the vulnerable WordPress installation. An attacker can exploit this vulnerability by:

1. Identifying endpoints in the Sweet Jane theme that process file inclusion parameters
2. Injecting directory traversal sequences (e.g., ../../../) to navigate outside the intended directory
3. Specifying paths to sensitive files such as /etc/passwd, wp-config.php, or application log files
4. Retrieving the contents of these files through the server's response or error messages

The vulnerability can be exploited remotely without authentication, making it accessible to any attacker who can reach the WordPress installation over the network. For detailed technical information, refer to the Patchstack WordPress Vulnerability Report.

Detection Methods for CVE-2026-22425

Indicators of Compromise

• Web server access logs containing directory traversal patterns such as ../, ..%2f, or %2e%2e/ in requests to Sweet Jane theme files
• Unusual file access patterns in PHP error logs indicating attempts to include system files
• Requests targeting theme endpoint URLs with file path parameters containing traversal sequences
• Evidence of wp-config.php or /etc/passwd content in response data or logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block requests containing directory traversal sequences
• Implement file integrity monitoring on critical WordPress files to detect unauthorized access or modifications
• Configure intrusion detection systems to alert on suspicious request patterns targeting WordPress theme endpoints
• Enable and monitor PHP error logging for include/require failures indicating exploitation attempts

Monitoring Recommendations

• Review web server access logs regularly for patterns indicative of LFI exploitation attempts
• Set up real-time alerting for requests containing common traversal payloads targeting the Sweet Jane theme
• Monitor WordPress file system access patterns using security plugins or host-based monitoring tools
• Implement centralized log aggregation to correlate suspicious activity across multiple WordPress installations

How to Mitigate CVE-2026-22425

Immediate Actions Required

• Deactivate the Sweet Jane theme immediately if a patched version is not available
• Switch to a secure, well-maintained WordPress theme as a temporary measure
• Review web server logs for signs of past exploitation attempts
• Audit any sensitive files that may have been exposed through this vulnerability
• Consider rotating database credentials and WordPress authentication keys if compromise is suspected

Patch Information

No official patch information is currently available in the NVD database. Organizations should monitor the Patchstack WordPress Vulnerability Report for updates on remediation options. Contact Elated-Themes directly for information about security updates for the Sweet Jane theme.

Workarounds

• Implement WAF rules to block requests containing directory traversal patterns targeting theme endpoints
• Restrict file system permissions to limit the impact of potential file inclusion attacks
• Use PHP open_basedir configuration to restrict file access to the WordPress installation directory
• Deploy .htaccess rules to block suspicious request patterns at the web server level

# Example .htaccess rules to block common LFI patterns
# Add to WordPress root directory .htaccess file
