Executive Summary

CVE-2026-22416 is a Local File Inclusion (LFI) vulnerability in the WordPress FixTeam Theme versions up to and including 1.4. It allows unauthenticated attackers to include and display local files from the target website by exploiting improper control of filenames in PHP include/require statements.

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

Mitigation Strategies

Since no official patch is currently available for CVE-2026-22416, immediate mitigation involves implementing the Patchstack mitigation rule designed to block attacks exploiting this Local File Inclusion vulnerability.

Users are strongly advised to apply this mitigation immediately to protect their websites from unauthenticated attackers who could otherwise include and display local files, potentially leading to sensitive information disclosure or database takeover.

Additionally, monitoring and restricting access to vulnerable theme files, disabling or restricting the use of the affected theme until a patch is released, and employing web application firewalls with updated rules can help reduce risk.
