CVE-2026-22496: Hypnotherapy Theme File Inclusion Flaw

CVE-2026-22496 Overview

CVE-2026-22496 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability affecting the AncoraThemes Hypnotherapy WordPress theme. This Local File Inclusion (LFI) vulnerability allows attackers to manipulate file path parameters used in PHP include or require statements, potentially leading to unauthorized access to sensitive files on the server or remote code execution under certain conditions.

Critical Impact

This LFI vulnerability can enable attackers to read sensitive configuration files, access credentials, or achieve code execution on WordPress installations running vulnerable versions of the Hypnotherapy theme.

Affected Products

• AncoraThemes Hypnotherapy WordPress Theme version 1.2.10 and earlier
• WordPress installations using the vulnerable Hypnotherapy theme
• Web servers hosting affected WordPress sites

Technical Details for CVE-2026-22496

Vulnerability Analysis

This vulnerability stems from improper sanitization of user-controlled input that is subsequently used in PHP file inclusion functions (include, include_once, require, or require_once). When the Hypnotherapy theme processes certain requests, it fails to adequately validate or sanitize file path parameters before including them in PHP execution context.

The attack can be executed remotely over the network, though exploitation complexity is considered high due to potential environmental prerequisites. Successful exploitation requires no privileges or user interaction, making it particularly dangerous for publicly accessible WordPress installations.

Root Cause

The root cause is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The vulnerability exists because the Hypnotherapy theme accepts user-supplied input for file path construction without implementing proper validation controls. This allows attackers to craft malicious requests containing path traversal sequences (such as ../) or other techniques to include arbitrary local files.

Attack Vector

The attack vector is network-based, allowing remote exploitation. An attacker can craft HTTP requests containing manipulated file path parameters that traverse outside the intended directory structure. By including sensitive system files like /etc/passwd on Linux systems or WordPress configuration files like wp-config.php, attackers can extract credentials and sensitive information.

In scenarios where file upload functionality exists or log files can be poisoned with PHP code, this LFI vulnerability can be escalated to achieve remote code execution. The vulnerability affects Hypnotherapy theme versions from the earliest release through version 1.2.10.

Detection Methods for CVE-2026-22496

Indicators of Compromise

• Unusual HTTP requests containing path traversal sequences (../, ..%2f, ..%252f) targeting theme files
• Web server logs showing requests attempting to include system files such as /etc/passwd or wp-config.php
• Unexpected file access patterns in WordPress theme directories
• PHP error logs indicating failed file inclusion attempts from non-standard paths

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in requests to the Hypnotherapy theme
• Monitor Apache/Nginx access logs for suspicious requests containing directory traversal sequences
• Deploy file integrity monitoring on WordPress installations to detect unauthorized configuration access
• Use SentinelOne's behavioral AI to identify anomalous file access patterns indicative of LFI exploitation

Monitoring Recommendations

• Enable verbose logging for WordPress and PHP to capture file inclusion operations
• Set up alerts for requests containing encoded path traversal sequences targeting theme endpoints
• Monitor for unusual outbound connections that may indicate successful data exfiltration following LFI exploitation
• Implement centralized log analysis to correlate potential LFI attempts across multiple WordPress installations

How to Mitigate CVE-2026-22496

Immediate Actions Required

• Review installed WordPress themes and identify any installations of the Hypnotherapy theme version 1.2.10 or earlier
• Consider temporarily disabling or replacing the Hypnotherapy theme until a patched version is available
• Implement WAF rules to block path traversal patterns targeting your WordPress installation
• Audit server logs for evidence of previous exploitation attempts

Patch Information

Check the Patchstack WordPress Vulnerability Database for the latest information on available patches and updates from AncoraThemes. Ensure you update to a patched version as soon as one becomes available from the vendor.

Workarounds

• Implement strict input validation at the web server level using ModSecurity or similar WAF solutions to reject requests with path traversal patterns
• Configure PHP open_basedir directive to restrict file inclusion to the WordPress directory tree
• Use disable_functions in php.ini to limit dangerous PHP functions if not required
• Apply the principle of least privilege to web server file permissions, ensuring PHP processes cannot read sensitive system files

# Example PHP configuration hardening for php.ini
open_basedir = /var/www/html/wordpress/
disable_functions = exec,passthru,shell_exec,system,proc_open,popen
