The AncoraThemes Tooth Fairy plugin for WordPress versions up to 1.16 contains a vulnerability where the filename used in PHP include or require statements is not properly controlled. This improper control allows an attacker to perform Local File Inclusion (LFI), which can lead to execution of arbitrary code or disclosure of sensitive files on the server. The CVSS v3.1 base score is 8.1, indicating high severity with network attack vector, high attack complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to an attacker including and executing arbitrary local files on the server hosting the Tooth Fairy plugin. This can result in full compromise of the affected system's confidentiality, integrity, and availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
