CVE-2025-69066: Indoor Plants WordPress LFI Vulnerability

CVE-2025-69066 Overview

CVE-2025-69066 is a Local File Inclusion (LFI) vulnerability affecting the AncoraThemes Indoor Plants WordPress theme. This vulnerability arises from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files from the server's filesystem.

Critical Impact

Attackers can exploit this LFI vulnerability to read sensitive configuration files, access credentials stored on the server, or potentially escalate to remote code execution by including malicious files or log files containing injected code.

Affected Products

• AncoraThemes Indoor Plants WordPress Theme versions up to and including 1.2.7

Technical Details for CVE-2025-69066

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Indoor Plants WordPress theme fails to properly validate or sanitize user-supplied input that is subsequently used in PHP file inclusion operations.

Local File Inclusion vulnerabilities in WordPress themes typically occur when theme functionality accepts a filename parameter—often through URL parameters, POST data, or AJAX requests—and passes it directly to include(), require(), include_once(), or require_once() functions without adequate path validation.

Root Cause

The root cause stems from insufficient input validation in the theme's PHP code. When user-controllable data is used to construct file paths for inclusion statements, attackers can manipulate these inputs using directory traversal sequences (such as ../) to navigate outside the intended directory and access sensitive files on the server.

The theme likely processes template or component loading requests without properly restricting the allowable file paths, enabling attackers to traverse directories and include files outside the intended scope.

Attack Vector

An attacker can exploit this vulnerability by manipulating input parameters that control which files are included by the theme. By injecting directory traversal sequences, the attacker can navigate the filesystem and include sensitive files such as:

• WordPress configuration files (wp-config.php) containing database credentials
• System files like /etc/passwd for user enumeration
• Log files that may contain previously injected malicious PHP code
• Other sensitive application configuration files

The exploitation typically requires the attacker to identify the vulnerable parameter and craft requests that traverse directories to reach the target file. Combined with log poisoning techniques, this LFI vulnerability could potentially be escalated to remote code execution.

Detection Methods for CVE-2025-69066

Indicators of Compromise

• Unusual HTTP requests containing directory traversal patterns such as ../, ..%2f, or ....// targeting WordPress theme endpoints
• Web server access logs showing requests attempting to access /etc/passwd, wp-config.php, or other sensitive files through theme parameters
• Error logs indicating PHP file inclusion failures for non-existent or inaccessible files
• Requests containing null byte sequences (%00) or encoding variations attempting to bypass filters

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block requests containing directory traversal patterns
• Monitor web server logs for suspicious requests targeting the Indoor Plants theme with path manipulation attempts
• Deploy file integrity monitoring on critical WordPress files to detect unauthorized access or modifications
• Review PHP error logs for include/require errors that may indicate exploitation attempts

Monitoring Recommendations

• Enable verbose logging on WordPress installations using the Indoor Plants theme
• Set up alerts for any requests containing encoded directory traversal sequences targeting theme files
• Monitor for unusual file access patterns on the web server, particularly attempts to read configuration files
• Implement real-time log analysis to detect exploitation patterns

How to Mitigate CVE-2025-69066

Immediate Actions Required

• Update the Indoor Plants WordPress theme to the latest available version that addresses this vulnerability
• If no patch is available, consider temporarily disabling or replacing the vulnerable theme
• Implement WAF rules to block requests containing directory traversal patterns
• Review web server access logs for signs of prior exploitation attempts
• Audit file permissions to ensure sensitive files are not readable by the web server process

Patch Information

Check with AncoraThemes for an updated version of the Indoor Plants theme that addresses this Local File Inclusion vulnerability. Monitor the Patchstack WordPress Vulnerability Report for patch availability and additional remediation guidance.

Workarounds

• Implement strict input validation at the server level to reject requests containing directory traversal sequences
• Deploy a Web Application Firewall configured to block LFI attack patterns
• Restrict PHP's open_basedir directive to limit file access to the WordPress installation directory
• Consider disabling unused theme features that may process user-controllable file paths

# Example PHP configuration to restrict file access
# Add to php.ini or .htaccess for additional protection
php_value open_basedir "/var/www/html/wordpress/"
