CVE-2025-67934: Wellspring Theme LFI Vulnerability

CVE-2025-67934 Overview

CVE-2025-67934 is a Local File Inclusion (LFI) vulnerability discovered in the Mikado-Themes Wellspring WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files from the server's filesystem. This can lead to sensitive information disclosure and potentially enable further exploitation of the affected system.

Critical Impact

Attackers can exploit this vulnerability to read sensitive configuration files, access credentials, and potentially escalate their attack to achieve code execution on vulnerable WordPress installations.

Affected Products

• Mikado-Themes Wellspring WordPress Theme versions prior to 2.8
• WordPress installations using vulnerable Wellspring theme versions

Technical Details for CVE-2025-67934

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Wellspring WordPress theme fails to properly sanitize user-controlled input before using it in PHP file inclusion operations. When an attacker supplies a maliciously crafted filename parameter, the application blindly incorporates it into include or require statements, enabling the attacker to read arbitrary files from the local filesystem.

The attack can be executed remotely over the network and requires user interaction. Upon successful exploitation, attackers can achieve unauthorized read access to sensitive files containing configuration data, database credentials, and other protected information stored on the server.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and sanitization of user-supplied parameters that control file paths in PHP include/require operations. The theme fails to implement proper allowlist validation or path canonicalization, allowing directory traversal sequences and arbitrary file paths to be processed by the inclusion functions.

Attack Vector

The vulnerability is exploitable via the network with low attack complexity. An attacker can craft malicious requests targeting the vulnerable file inclusion functionality in the Wellspring theme. By manipulating filename parameters with path traversal sequences (such as ../), attackers can escape the intended directory and include sensitive system files like /etc/passwd, WordPress configuration files (wp-config.php), or other files containing credentials and sensitive information.

The attack typically involves sending specially crafted HTTP requests to the vulnerable WordPress endpoint, where the malicious filename parameter is processed without adequate validation. While user interaction is required for exploitation, the impact is significant as it can expose highly confidential data and potentially lead to further system compromise.

Detection Methods for CVE-2025-67934

Indicators of Compromise

• Unusual HTTP requests containing path traversal sequences (../, ..%2F, %2e%2e/) targeting WordPress theme endpoints
• Web server access logs showing attempts to access sensitive files via Wellspring theme parameters
• Anomalous file read operations from the web server process targeting configuration or system files
• Error log entries indicating failed file inclusion attempts with unusual path patterns

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in request parameters
• Monitor web server access logs for requests containing directory traversal sequences targeting the Wellspring theme
• Deploy file integrity monitoring to detect unauthorized access to sensitive configuration files
• Configure intrusion detection systems to alert on LFI attack patterns targeting WordPress installations

Monitoring Recommendations

• Enable detailed logging for PHP file operations and include statements on WordPress servers
• Set up alerts for access attempts to sensitive files such as wp-config.php from web-accessible paths
• Monitor for unusual patterns in web traffic targeting WordPress theme directories
• Review server logs regularly for failed file access attempts that may indicate exploitation attempts

How to Mitigate CVE-2025-67934

Immediate Actions Required

• Update the Wellspring WordPress theme to version 2.8 or later immediately
• Audit WordPress installations to identify all instances using vulnerable Wellspring theme versions
• Review web server access logs for evidence of exploitation attempts
• Consider temporarily disabling the Wellspring theme until patching is complete if immediate update is not possible

Patch Information

The vulnerability has been addressed in Wellspring theme version 2.8. Website administrators should update to this version or later through the WordPress theme management interface or by downloading the latest version directly from the theme vendor. Detailed vulnerability information is available in the Patchstack Vulnerability Report.

Workarounds

• Implement Web Application Firewall rules to block requests containing path traversal sequences targeting the Wellspring theme
• Restrict file system permissions to limit what files the web server process can access
• Use PHP configuration options like open_basedir to restrict file inclusion to specific directories
• Consider using a security plugin to add additional input validation layers to WordPress
