CVE-2025-31632: La Boom PHP File Inclusion Vulnerability

CVE-2025-31632 Overview

CVE-2025-31632 is a Local File Inclusion (LFI) vulnerability in the SpyroPress La Boom WordPress theme. The vulnerability stems from improper control of filename for include/require statements in PHP, classified under CWE-98 (PHP Remote File Inclusion). This weakness allows attackers to include local files on the server by manipulating input parameters that are used in PHP include or require statements without proper validation.

Critical Impact

Successful exploitation of this vulnerability could allow unauthenticated attackers to read sensitive files from the server, potentially exposing configuration files, database credentials, and other confidential information. In certain configurations, this could lead to remote code execution.

Affected Products

• SpyroPress La Boom WordPress Theme version 2.7 and earlier
• WordPress installations running vulnerable versions of La Boom theme

Technical Details for CVE-2025-31632

Vulnerability Analysis

This vulnerability exists due to improper validation of user-supplied input in the La Boom WordPress theme developed by SpyroPress. The affected component fails to properly sanitize filename parameters before passing them to PHP's include() or require() functions, allowing attackers to traverse directories and include arbitrary local files.

Local File Inclusion vulnerabilities in WordPress themes are particularly dangerous because WordPress installations often contain sensitive files such as wp-config.php which stores database credentials, and various plugin configuration files that may contain API keys or other secrets.

Root Cause

The root cause of CVE-2025-31632 is the lack of proper input validation and sanitization in the La Boom theme's file inclusion logic. When user-controlled input is directly concatenated into file paths used in PHP include statements without adequate filtering, attackers can manipulate these paths using directory traversal sequences (such as ../) to access files outside the intended directory scope.

Attack Vector

The vulnerability is exploitable over the network without requiring authentication or user interaction. An attacker can craft malicious HTTP requests containing directory traversal sequences to include sensitive local files. The attack complexity is considered high due to specific conditions that may need to be met for successful exploitation.

The exploitation mechanism involves manipulating file path parameters to include arbitrary files from the server filesystem. Attackers typically target files such as /etc/passwd, WordPress configuration files, or log files that may contain sensitive information. For detailed technical information, refer to the Patchstack vulnerability database entry.

Detection Methods for CVE-2025-31632

Indicators of Compromise

• Unusual HTTP requests containing directory traversal sequences such as ../ or ..%2f targeting theme files
• Web server access logs showing attempts to access sensitive system files through theme endpoints
• Unexpected file access patterns in WordPress theme directories
• Error logs indicating failed file inclusion attempts or PHP warnings related to include statements

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block directory traversal patterns in HTTP requests
• Monitor WordPress access logs for requests containing path manipulation attempts targeting /wp-content/themes/laboom/
• Implement file integrity monitoring on critical WordPress configuration files
• Use intrusion detection systems configured with signatures for PHP LFI exploitation patterns

Monitoring Recommendations

• Enable verbose logging for WordPress and web server to capture detailed request information
• Set up alerts for unusual file access patterns on the web server
• Monitor for reconnaissance activity targeting WordPress theme detection endpoints
• Implement real-time log analysis for common LFI payload signatures

How to Mitigate CVE-2025-31632

Immediate Actions Required

• Update the La Boom WordPress theme to a patched version if available from SpyroPress
• If no patch is available, consider disabling or removing the La Boom theme until a fix is released
• Implement WAF rules to block directory traversal attempts targeting WordPress theme files
• Review server access logs for signs of exploitation attempts

Patch Information

Users should check the SpyroPress vendor website or the WordPress theme repository for security updates addressing this vulnerability. The Patchstack advisory provides additional details on remediation options.

Workarounds

• Implement strict input validation using a whitelist approach for any file inclusion parameters
• Deploy ModSecurity or similar WAF with rules to block path traversal sequences
• Restrict filesystem permissions to limit readable files from the web server context
• Consider switching to an alternative WordPress theme that is actively maintained and security audited

# ModSecurity rule example to block directory traversal attempts
