Executive Summary

CVE-2026-22378 is a Local File Inclusion (LFI) vulnerability in the WordPress Blabber Theme versions up to and including 1.7.0. It allows an unauthenticated attacker 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 potentially access sensitive files on the server, such as configuration files or database credentials, by tricking the application into including those files.

Detection Guidance

CVE-2026-22378 is a Local File Inclusion (LFI) vulnerability in the WordPress Blabber Theme up to version 1.7.0 that allows unauthenticated attackers to include and display local files. Detection typically involves monitoring for suspicious HTTP requests attempting to exploit the include/require statements.

While no specific commands are provided in the available resources, common detection methods include inspecting web server logs for unusual URL parameters that attempt to include local files, such as requests containing directory traversal patterns (e.g., ../) or attempts to access sensitive files like /etc/passwd.

Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to detect and alert on such suspicious requests.
