The vulnerability CVE-2026-22416 affects AncoraThemes FixTeam versions up to 1.5.0 and arises from improper control over filenames used in PHP include or require statements. This improper control can lead to PHP Local File Inclusion, where an attacker may cause the application to include unintended files, potentially leading to remote code execution or disclosure of sensitive information. The CVSS 3.1 base score is 8.1, reflecting network attack vector, high attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an unauthenticated attacker to include local files on the server, potentially leading to arbitrary code execution, data disclosure, or denial of service. The high CVSS score reflects the critical nature of these impacts. However, no known exploits have been reported in the wild so far.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to vulnerable endpoints, applying web application firewall rules to detect and block suspicious include requests, and limiting file permissions to reduce the impact of potential exploitation.
