The vulnerability CVE-2026-28069 in ThemeREX Le Truffe involves improper control over the filename parameter used in PHP include or require statements, resulting in a Local File Inclusion (LFI) vulnerability. This flaw exists in versions up to 1.1.7 of Le Truffe. An attacker could exploit this to include arbitrary local files, potentially leading to disclosure of sensitive information or remote code execution depending on the context. The CVSS v3.1 score is 8.1, indicating high severity with network attack vector, high impact on confidentiality, integrity, and availability, but requiring high attack complexity and no privileges or user interaction.

Successful exploitation of this vulnerability could allow an unauthenticated attacker to include and execute local files on the affected server, leading to full compromise of the system's confidentiality, integrity, and availability. This could result in data disclosure, code execution, or denial of service. However, no known exploits are currently reported in the wild.

No official patch or remediation guidance is currently available for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
