Executive Summary

CVE-2026-22424 is a Local File Inclusion (LFI) vulnerability in the WordPress Shaha Theme versions up to and including 1.1.2. It allows unauthenticated attackers to include and display local files from the target website by exploiting improper control of filename for include/require statements in PHP.

This means an attacker can trick the application into loading files from the server that should not be accessible, potentially exposing sensitive information.

Detection Guidance

[{'type': 'paragraph', 'content': 'CVE-2026-22424 is a Local File Inclusion (LFI) vulnerability affecting the WordPress Shaha Theme up to version 1.1.2. Detection typically involves monitoring for attempts to exploit the vulnerability by including local files via crafted HTTP requests targeting the vulnerable include/require statements.'}, {'type': 'paragraph', 'content': 'While no specific detection commands are provided, common approaches include inspecting web server logs for suspicious requests containing file path traversal patterns (e.g., ../ or %2e%2e%2f) or unusual parameters attempting to include local files.'}, {'type': 'paragraph', 'content': 'Network or system administrators can use tools like grep to search access logs for such patterns. For example:'}, {'type': 'list_item', 'content': 'grep -iE "(\\.{2}/|%2e%2e%2f)" /var/log/apache2/access.log'}, {'type': 'list_item', 'content': 'grep -i "include" /var/log/apache2/access.log'}, {'type': 'paragraph', 'content': 'Additionally, web application firewalls (WAFs) or intrusion detection systems (IDS) can be configured to detect and alert on LFI attack patterns.'}] [1]

Mitigation Strategies

Since no official patch is currently available for the Shaha theme vulnerability, immediate mitigation involves applying the Patchstack mitigation rule designed to block attacks exploiting this Local File Inclusion vulnerability.

Users are strongly advised to implement Patchstack’s mitigation measures as soon as possible to protect their websites from potential exploitation.

Other general mitigation steps include:

• Restrict file permissions to limit access to sensitive files.
• Use a web application firewall (WAF) to block suspicious requests.
• Monitor logs for exploitation attempts and respond accordingly.

Ultimately, update the theme to a patched version once it becomes available.
