This vulnerability in TangibleWP Listivo Core arises from improper validation or control of filenames used in PHP include or require statements, enabling PHP Local File Inclusion. This can allow an attacker to include unintended files on the server, potentially leading to code execution or information disclosure. The issue affects all versions up to and including 2.3.77. The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.

Successful exploitation can lead to local file inclusion, which may allow attackers to execute arbitrary code, disclose sensitive information, or disrupt service. The high CVSS score reflects the potential for severe impact on affected systems. No known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor TangibleWP advisories for updates. Until a fix is available, restricting access to vulnerable endpoints and applying strict input validation may help reduce risk.
